Luck is the best, by far, and it isn't close.
I don't think so. He may be the better QB, but not by far. If I had to pick, I'd pick Wilson right now. Luck had too many turnovers, which is normal for a rookie starting QB. Russell didn't. Luck had far more passing yards than Russell, but thats because Seahawks were a far superior run team than Colts. They didn't have to throw as much. This is evident by the number of TDs to attempts ratio each player had:
Andrew Luck 23 in 627 attempts (27.26 attempts per TD)
Russell Wilson 26 in 393 attempts (15.11 attempts per TD, almost half of Luck)
Stats don't tell the whole story. The only knock on Russell was that he was considered too short to play the game and didn't have downfield vision. I think after running for almost 500 yards and passing at over 100 QB rating, that notion can be dismissed. I'd build my team around Wilson as well (or Kapernick). QB position is evolving in to a scrambling QB. Brady has next to no mobility. If he was even 10% of Russell or Kaep, he would have had several more rings.
