Don't you think having Mariota might have made it a little easy for his transition to HC? He stepped into Chip's system with Chip's players. I don't think we'll truly see how good Helf is until next season without Mariota and with a team that is entirely (?) recruited by him. Obviously a lot of the key players are freshman this year, so that's already really impressive. Nelson and Royce have been amazing, but Mariota erases a lot of sins and I don't think we'll truly see Helf earn his paycheck until he breaks in a new QB next year.
