I don't understand some of you posters. Last year, PN was lauded for his halftime adjustments and ability to win close games. See 4 straight close wins early, and some 2nd half comebacks later. Now, he doesn't know how to adjust because he has lost some close games. I am not a football coach, and not observant enough to scrutinize his strategy within games, but I watched the VT game over again and saw DBs right there in coverage. They lost jump balls and at times don't turn their heads resulting in PI penalties. But, it seems to be a matter of technique in finishing and the fact they are so much shorter in height. Also, a former HS coach told me (I have asked some of the same questions as on here), that there are subtle adjustments being made by the staff, but the players aren't always good enough to consistently make them work. So take this post for what it is worth, but this 'not making adjustments, and changing scheme' references are overexaggerated IMO.
