I dunno, Val. It's just been a long time since we've seen REAL development of a player over the course of 3 or 4 seasons.
Chubba Purdy's Redshirt Freshman stats weren't bad. He managed to get some serious playing time - 6 games with 2 starts and had okay stats for playing behind a horrible OL: 22-48 passes for 147 yards - rushed 24 times for 73 yards and 2 TDs.
That's better than another Redshirt Freshman's first season who played at another B1G school: 1 game - 0 starts - 3-5 for 26 yards - 1 interception - no rushes. That was Tom Brady's first season at Michigan.
