Read some ridiculous comments about how Rico McGraw running out on the field without his helmet, leading to a crucial 15 yd penalty, should be blamed on coaches. Likewise, Georgia's inability to knock down a hail Mary pass was due to poor coaching.
When you have one guy (I guess a second in street clothes made his way out there) out of nearly a hundred doing something like that, it's the fault of an individual player. Perhaps next time the coaches should put shock collars on everyone if it's their fault.
As for misplaying the Hail Mary, I can say with a high degree of certainty that that scenario is practiced (properly) many times before and during the season. The only potential change I could see would be having a few taller folks out there. Maybe put Javon Wims, the 6'4-6'5 WR planted on the goal line, but that's splitting hairs. The bottom line is that UT's WR got in just the right spot, and our players did not.
Hell, I can look at Georgia's touchdown prior to the heartbreaking Hail Mary and tell you that UT's DB was probably given explicit instructions: "Do NOT let them get behind you, whatever you do." But, their DB got lulled to sleep by Ridley, who then turned on a burst to catch a long TD.
All this is not to say that the coaches don't have their share of responsibility in these cases. It is, of course, up to them to make sure they're not only teaching their players what to do and what not to do, but that they get players to respond and execute.
Kirby cites a lack of discipline. It is ultimately up to the coaches to make sure the players are exhibiting said discipline, but no matter who you are as a coach, in the moment, sometimes players just don't do what they're supposed to or need to do.
This loss, while devastating to me as a fan, will be a better teacher than any coach or drill can be going forward.
