It's not necessary underwhelming.
He was the OC and QB coach at Stanford when Andrew Luck was there.
In Luck's second year in Indy, he was brought in to be the OC.
The Colts improved in his first two years, but did not do well in 2015 when he got fired mid-season with Luck injured.
But really, that team was all about Andrew Luck; Frank Gore was getting long in the tooth.
The Colts perform when Luck was in there; that's pretty much sum it up.
Without Luck, the Colts never did any better than with Pep.
Pep also got some credit for being the QB coach for Justin Herbert, who had a good rookie season.
He was selected to be in the NFL Accelerator Program for coaching so he couldn't be bad.
But he decided to join the NFL Network.
I don't think Pep is a great OC, but he wasn't too shabby either.
The Texans just didn't have the talent to compete last year.
