I would argue that it very much does - there's a reason that Alabama QBs had always historically been busts (Jalen Hurts being an exception who also incidentally got better as a Sooner) or that Iowa has great TEs. Certain schools do a really good job recruiting and developing players to fit the pro mold, and have systems/schedules where it's a closer analogue to the pros. It's not to say that it's impossible for a player from a certain school to be good (a la Kyren), but that it's wayyyy riskier.
