Eh, it's not like he spiked the ball, like the Lions did in their playoff game against the buccaneers, or Rutgers did against Michigan State a couple years ago. He thought there was another play, but I'm not sure it actually changed anything.
The main issue is just that he and Gronk are both too old. Hell, most guys hung it up with far less wear and tear on their bodies than those two have. He and Brees have it in flashes, but there's a reason there aren't 40+ year old players in the league with regularity.
