So does all this crap mean that that you agree it is time to move on from Mack? If so, welcome aboard.
I'll give you a little hint about teaching DBs when and when not to look back for the ball. When a DB is beaten, he should not look back until such time as the receiver is clearly moving hands to make the catch, and then he almost always is better off just going for those hands. Why? Because in looking back, he loses another fraction of a step, and if the receiver catches the ball, he then is gone.
Bly never had to think about such matters playing, because in college almost no one, ever, beat him and got a full step behind him. The reason the DBs tend to play so far off the LOS is because they lack the techniques to be able to keep up with quality receivers. They also, save for a couple of freshmen who clearly are Warren's type, have major issues with tackling in open space.
As for that UNC-Pitt game in 2022, do you think that if the teams had played again, in Pittsburgh, this week, that UNC would have won? Pitt was the better team to end the season and has as many wins overall and has a better best win. failure not to grasp those things means fans have a false rosy picture about the state of the program under Mack. .
