Ryan Tannehill was a very good WR for the Aggies and they switched him to QB mid-season (something the game doesn't allow) and he lit it up at QB. The reverse happened for the Longhorns, John Chiles was a QB who switched to WR.
This can NEVER happen in the game.
Actually this is the one I see a lot of. But it's when I recruit QB I look on my depth chart and they are like my 4th or 5th wr. I actually have let my 3rd string qb play wr.
