i firmly believe that the Wonderlic has direct correlation with processing speed.
I re-watched the LSU v Bama game on SEC just the other night.
It is clear as day when you re-watch that Tua RARELY comes off his first read ( unless pressured and exits the pocket ). There was maybe a handful of times where you could see him progressing thru routes. MAybe 4-6 times out of 40 or so passes.
And in college, you can get away with that especially if you have a WR like Juedy matched up against a 3 star sophmore from UT or Vandy.
Not in the NFL.
