FOXBORO -- It could have been that he's been splitting first-team reps with Jimmy Garoppolo. It could have been that he had just thrown a pass that was batted down by a ball boy holding a paddle. It could have been that he's simply operating at a low boil at all times now knowing that he has to serve a four-game suspension.
Whatever the reason, Tom Brady was hot. And he took it out on his helmet Friday, slamming it to the turf -- with ear pads exploding out upon impact -- after the final snap of the 7-on-7 period at Patriots practice.
It was the most noteworthy show of frustration during what appeared to be a highly-competitive day of work for Bill Belichick's club. Just two days into practice, and one day before the first day of work in full pads, there was a visible emotional edge exhibited by several players on the team.
"That's just football," tight end Martellus Bennett said. "It is what it is. I like guys that have an edge, and I think a lot of guys on this team have an edge. When they have that edge, it makes you bring it up a notch, too."
Bennett may have helped to amp things up when he caught a touchdown pass over Patrick Chung from Jimmy Garoppolo. He used his 6-foot-7 frame to go up and over Chung, and then kept his balance as he corralled the ball with Chung down around his feet. When the play was over Bennett, dropped the ball by Chung while Chung was on the ground.
Later in the practice, Rob Gronkowski caught a touchdown on a back-shoulder throw from Garoppolo with Jordan Richards in coverage. Gronkowski promptly threw the ball in the air in celebration, which seemed to irk Dont'a Hightower. The linebacker quickly retrieved the ball and chucked it at Gronkowski's back.
Brady's helmet slam came on a short pass that was batted down by one of the paddles made to simulate long-armed defensive linemen. He hadn't looked very shaky leading up to that point, completing 7-of-9 passes, though one of those attempts resulted in a Duron Harmon interception. But two incompletions to finish his 7-on-7 stretch led to the helmet slam that drew an audible reaction from surprised fans in attendance.
Brady's reps and their timing drew considerable attention yet again. In a switch from Thursday's practice, it was Brady who took the first-team reps during 11-on-11 work, while Garoppolo was the first on the field during the 7-on-7 portion of practice. Each player got 10 snaps in 7-on-7 work and seven snaps in 11-on-11 work so the workload was once again split evenly.
In analyzing the results for both quarterbacks, Garoppolo went 9-for-10 in 7-on-7 work, while Brady went 7-for-10 with an interception during the same period. In the 11-on-11 portion of practice -- after the helmet spike -- Brady went 5-for-7. Garoppolo went 4-for-7, and Jacoby Brissett went 4-for-7 with an interception made by linebacker Kevin Snyder on a deflection from corner Darryl Roberts.
It's not unusual for competitive moments -- and accompanying emotional outbursts -- to transpire during camp. That it's happening already with the Patriots could foreshadow weeks of such moments, which, given the talent level the team currently boasts on its roster, perhaps should be expected.
When both sides of the football have as many accomplished players as the Patriots do, and when both sides are executing, the level of play tends to rise. With that, the competitive juices often do the same.
"Every single day I've been here since OTAs it's been very competitive," Bennett said. "Everyone here does their jobs so well, and everyone's competing. You just gotta bring it every single day."
That may not be good news for the equipment staff that has to deal with the fallout of busted gear. But for coach Belichick, who has long called training camp the "competition camp" (as opposed to OTAs and minicamp, which is more of a "teaching camp"), it's probably music to his ears.
