I realize that Chip Kelly is a better offensive coach than our Kelly. But it's the third year in the program for Golson, Atkinson, Daniels, Hegarty, Hanratty, N. Martin, McDaniel etc. If Kelly wants to run up-tempo, I don't think he can rely on personnel and youth as excuses. Perhaps Golson still doesn't have sufficient command of the offense, but if that's the case, that's on Kelly and Golson. A third year player and second year starter should be able to run the full offense.
Not to mention The fourth year for Martin, Watt, Lombard and Jones.
