I think he will. Urban's really come around for me. I despised him at Florida because of the 30+ arrests and everyone just talked Tebow. He was very complimentary of IU during his time at Ohio St and recently....and honestly when he's talking football I learn something from him. He has an owner who is tired of being a laughingstock, tons of picks and cap space and the best pro ready qb to hit the NFL since Andrew Luck.
I guess we should define successful but I think successful there would be making the playoffs in 2 years...and consistently from there. Unless Mahomes gets hurt I don't see many taking multiple titles from them over coming years. Colts could have but Luck bailed on his team.
