It will be a genius move if it works, and it won't be a genius move if it doesn't. But that's all yet to be seen.
I'll say this in their favor... if indeed he was that highly rated on their draft board, the fact that he's under contract long enough to get a full assessment makes him worth a 5th for sure, and then if a 5th for sure, then a 4th possibly... again... if he proves to be an asset.
Yes, he's going to get fewer snaps now, but then again, you're probably going to (unfortunately) have enough injuries over the course of 17 games that Mingo will have a chance to show out.
Cliffs notes: The jury is going to meeting for most of this next season before rendering a legit verdict on that question.
