I was thinking about this a little more last night after talking to my FIL in Madison. Crazy to think this appears to be down to Wisconsin and USC for Caleb Williams and there really isn't anything you can point to that gives Wisconsin an advantage over USC when recruiting a QB.
However, it occurred to me that Wisconsin's OL coach/OC, Joe Rudolph, left to be the OL coach at VaTech (making me believe Chryst encouraged him to move on), and Chryst is likely bringing in Bobby Engram to be the new OC. Engram was the WR coach under Chryst at Pitt and is currently the Ravens' TE coach.
Pair these moves at key offensive staff positions, a new AD at UW with Alvarez no longer running the show (at least publicly), increasingly lackluster offensive performances over the last couple seasons, the program falling short of expectations, and now the rumors of the top QB transfer and former 5* recruit Caleb Williams being courted and seriously entertaining the idea, and I am wondering if we are about to see Wisconsin enter the modern age of offensive football.
TL/DR - I think there is evidence that Wisconsin could be moving to a modern offense, which could be part of the sell to Williams.
