He has not lost a game in two years for various reasons. First and formost, Jimbo Fisher is better than 90% of the head coaches out there. Next, florida State plays a soft schedule. He also has had some very good talent around him. He obviously is a head case, but Fisher has managed to keep him on a relatively straight course so far. We will see just how good he is next week, when he faces a red hot Tech team. Mariota is in a different zip code. As Oregon will find out next season, without him, Oregon is just your average good team, but nowheres close to a championshiip team. How he does in the NFL remains to be seen. Too many "can't miss" kids miss.
All you need to understand is what direction the Ducks have been headed since Kelly was hired to be Belotti's OC. The conference got an extra 20 mil+ per team from TV and Big Daddy threw down 10's of millions more just for the CFB Ducks. Recruits take one look at Oregon's training facilities and it's difficult to walk away. They've traditionally been loaded at the QB position -- Mariota could be the best but very highly talented Duck QB's go back years.
PS... I truly hate having to say this but Sarkisian is a huge pile of mediocrity.
