I haven't seen/read much, and there probably ought to be more? He's successfully lead the Eagles offense this year by hiding a middling throwing QB (Hurts) and putting the load onto Saquon. He had some very good years in DAL doing a little bit of the same. They were very highly ranked in points and yardage. He has a decent amount of the hallmarks you look for in a young coordinator; success in different schemes/ways, creative usage with plenty of motion and high pace, really good run game and some practical playing experience. He's not a bad guy to be talking to imo.
