As recruiting was wrapping up I had an extra scholarship so I decided to sign a STL QB who was considering me with 24 WE (Thomas Schultz). The thing is, he was the 3rd QB I signed this year and the worst of the 3 (currently). He won't see the field as a freshman (I promised another QB a starting spot), so I'll probably redshirt him. My question is, with that low WE and the fact that he's probably not going to play a lot early in his career, should I expect to see anything special out of him development-wise? Or will he develop just like any other backup QB with low WE since he's not getting PT?

I had a high potential QB with a WE of 18 (above average QB attributes). I started him as a RS FR. He had a WE of about 42 when he was done, and ended with good SR QB attributes because he started out so high.  So - even with STL - if he doesn't play - don't expect much growth beyond the average player.
