I disagree with all those who say that the commitment of a player or players was a turning point. Recruiting cannot be a turning point unless the coaching was there, but the talent wasn't. Say what you want about holes in Weis's recruiting; I don't think talent was Weis's main problem. Under Weis, we had probably the two best players I've ever seen in a ND uniform, Jimmy Clausen and Golden Tate, plus numerous others who got looks in the NFL, and we were still not reliable on offense. Frequent spectacular plays? Yes. Could you count on a big first down when you needed it? No. Look at USC this year. You have a team of five-stars and high four -stars, a team that unquestionably has the talent to compete for NCs, but which is just an above average football team. Look at Manti early in his career ... great athlete, but by his own admission not a great player. It took great coaching to make him a great player.
I think IrishinSyria probably had the best answer to this one, when he said the turning point was whenever we learned to tackle. Now, our defense played pretty well all year last year, so maybe that was spring practice 2011? Not sure. I don't think there was a real turning point you can specify. Diaco and his coaches just kept chopping wood with the defense, and now our defensive players just get it. The message has sunk in.
But even that isn't really a satisfying answer to the question of what the turning point was, because even with a solid D last year we lost a lot of games because our offense was mediocre. The improvement of the D by itself can't be the turning point, as long as the offense is still mediocre. The turning point will be whenever the offense steps up to match the high level performance of the D.
It's too recent to look like the turning point now, but I think in 2 or 3 years if we revisit this convo we'll say that the turning point was the 4th quarter and OT of the Pitt game, when Golson led his first comeback. That was the first time I've seen a QB look like he was in complete command of BK's offense, and he did it in a game in which he had played like total sh!t for the first three quarters. After the third quarter Golson showed heart and determination, he played with confidence, he looked comfortable. We always knew he had the talent, but we didn't know if he could lead us back from 15 points down to gut out an ugly win. Against OU he proved he could avoid beating his own team; against Pitt he proved he could win one. Now we know that we have a QB who has the skill set to effectively run the fullest version of BK's offense, as well as the toughness to lead the team to victory.
To me that's the turning point.
