I think it will be Jeff Grimes as OC/OL
Broyles Award Finalist with Baylor (OC/TE)
1st year OC at Baylor - 8th in nation in rush yards pg, and 4th in nation rush yards per attempt (Baylor was awful the year before Aranda hired him)
3 years previously he was OC at BYU (Zack Wilson, amazing offense)
That's telling that can be successful with a running style or passing game.
Also,
20 years as OL coach (LSU, Auburn Natl Champs, BYU, etc..)
When he played in college, his OL coach was Andy Reid.
He's an OL guy through and through, and a great OC.
Boost his pay from $500k to $1mil

Just a strong hunch. But if I am right, I want cookies and koolaid!
