Dr. M: With Shaq's injuries, size does matter

By Dr. Neil Minkoff
Special to CSNNE.com

Shaqs out. Again. Lots of nagging injuries have been bothering him. So far this season, hes had sore knees, bad hips, a painful Achilles tendon and now a foot injury.

Celtics fans dont even seem bothered by it. Sure, theres worry about the big guy in the playoffs, but most fans seem sympathetic to a middle-aged guy (he turned 39 Sunday) with nagging injuries still playing in the NBA.

Not me.

And heres why the issue is Shaqs size. The Big Diesel has become a Double-wide. Shaq needs to lose weight. There, I said it.

When a basketball player jumps, his knees and ankles are designed to act as shock absorbers to take the impact. This is a combination of the joints bending and cartilage flexing. There are even little sacs of fluid called bursas that absorb the force.

So thats what we need to focus on if we want to protect Shaqs knees, hips and ankles the force of the landing. Shaq is listed by the Celtics at 325 pounds. Please. I went back and looked at Shaq in his Magic and Laker days. My educated guess is that hes tipping the scales between 350 and 360 pounds, up maybe 50 pounds from when he entered the league. Thats under 3 pounds of gain a year they just add up.

His weight becomes magnified when you look at force of impact, though. Thats because you multiply the players weight by the effect of gravity pulling him to the floor to measure force of impact. The effect of gravity has been found to be 32.2. Thats right, each pound counts 32 times when measuring the force.

So say Shaq weighs 350 pounds. Every time he jumps, his legs absorb an amazing 11,270 pounds of force. This season, Shaq is averaging 5.5 FGA per game. Those are all dunks and lay-ups, so thats 61,985 pounds of force. Hes averaging 4.9 boards per game, so theres another 55,223 pounds of force. His 2.3 blocks per game add another 25,921 pounds of force. And we should assume another 5 jumps or so on block attempts and missed boards for another 56,350 pounds of force. Thats over 200,000 pounds of force every game.

Lets compare to another big guy to get a sense of how big this is. KG is listed at 220 pounds, which I can believe. The impact of each of his jumps is only 7,084. So KGs average game of 11.8 FGA (assume 8 dunks and lay-ups), 9.2 boards, 0.8 blocks and the same 5 assumed missed blocks and boards only comes up to 162,932 pounds of force. Look at that double the production of Shaq and way less force to deal with.

The big difference is the weight.

Heres another thing: Shaq has bad hips and a bad back. The pelvic bone is like a see-saw balanced on the hips - the more weight is piled in front, the more strain felt by the hips and lower back. I learned in med school that every extra pound a man carries on his gut means 10 pounds of pressure on the low back.

For the sake of argument, say Shaq split the difference between his Magic weight and his Celtic weight. Hed get down to 325, you know, the weight the Cs say he is.

That would be a reduction in impact force of 10 percent, which is huge. Would that lead to 10 percent more production? I say yes. Would that lead to 10 percent more games played? Once again, I say yes.

I never even got to the important reasons Shaq should lose weight heart disease, diabetes and stroke risk are the big ones. I just write about it from an injury point of view.

Cmon, Shaq. Lose the weight. Do it for your career. Do it for Celtics fans. Most importantly, do it for your kids.

Celtics-Knicks preview: Thomas scoring at record pace in fourth quarter

Celtics-Knicks preview: Thomas scoring at record pace in fourth quarter

WALTHAM, Mass. –  As the fourth quarter rolls around, you will occasionally catch Boston Celtics guard Isaiah Thomas looking down at his wrist, a gesture to remind anyone watching what time it is – Thomas time.

There are those who elevate their play in the fourth quarter of games, and then there’s Thomas who continues to smoothly navigate his way in unchartered fourth quarter scoring territory.

The Celtics begin the second half of the season Wednesday night against the New York Knicks, and there sits Thomas atop all players in the NBA when it comes to fourth-quarter scoring.

But that’s not all.

He’s not only dropping more points than any other NBA player in the most important quarter of them all, but he’s doing so at an unprecedented level of 10.1 fourth-quarter points per game.

Since NBA.com/stats began tracking fourth quarter scoring with the 1997-1998 season, no player has averaged more than 9.5 fourth-quarter points (LeBron James, 2006) in a season.

What makes Thomas’ fourth quarter heroics so impressive is that everyone in the building – fans, coaches, opponents – knows that’s when he’s looking to be most impactful for the Celtics and yet he still can’t be stopped.

Charlotte Hornets coach Steve Clifford acknowledged how tough it is to limit Thomas despite knowing he’s looking to take over games in the fourth.

“It’s hard because the blitz game is impossible because they don’t roll,” said Clifford whose Hornets were beaten 108-98 by Boston on Monday. “If you watch the teams that try to blitz them, you’re going to give up basically lay-ups. We had things in to get the ball out of his hands but the way they played and the stuff that they usually go to late, they didn’t get to. He (Thomas) made some terrific plays; he’s a terrific offensive player.”

Despite what he does in the fourth and his overall scoring average of 28.2 points which is ranked among the league’s leaders, there are still lots of doubters as to how good Thomas.

Regardless of how you view his play, he has consistently played at a level this season that places him among the game’s best players.

And at the rate he’s scoring in the fourth quarter, he’s establishing himself as one of the great closers in the game.

Consider the list of players in the past decade who led the league in points scored in the fourth quarter.

  • 2016: James Harden (7.7)
  • 2015: Russell Westbrook (7.1)
  • 2014: Kevin Durant (7.9)
  • 2013: Kevin Durant (8.4)
  • 2012: Kevin Durant (7.3)
  • 2011: Amare Stoudemire (7.1)
  • 2010: LeBron James (8.0)
  • 2009: LeBron James (7.7)
  • 2008: LeBron James (9.1)
  • 2007: Dwyane Wade (8.2)

You have All-stars, All-NBA First Teamers, league MVPs as well as a few future Hall of Famers.

As good as those players were in their respective seasons, when the game mattered most – the fourth quarter – Thomas numbers (for now at least) stand head and shoulders above them all.

Celtics coach Brad Stevens gives Thomas a lot of credit for being such a consistent scorer, particularly in the fourth quarter.

But as good as Thomas is, he’s not out there getting all these baskets on his own, either.

“It says a lot about the fact that he’s got a lot of skilled guys around him that are hard to leave,” Stevens said. “When you’re playing Kelly (Olynyk) and Jonas (Jerebko) together with him, there’s a lot of space on the floor to operate. When those guys are at the four (power forward) and five (center), when you’re playing guys like Al Horford who can space the floor or Avery (Bradley) or Jae (Crowder), you know, those types of guys … at the end of the day I think that it’s a combination of a lot of things.”

And for opponents, a lot of problems.

“He’s been playing well,” Hornets guard Kemba Walker said of Thomas. “He’s been playing better than anyone in our league. He’s playing with great confidence and making the plays for his team to win games. He’s been great.”
