Depth is critical along the offensive line. The new Michigan football coaching staff seems to know that as well as anyone, based on how they have operated this offseason.
Outside of quarterback Bryce Underwood, and upgrading the wide receiver position, keeping the offensive line intact was a top priority.
And it worked. Despite Andrew Sprague and Jake Guarnera entering the transfer portal for a short time, the Wolverines retained three of their five starters from last season. The two Michigan football didn't keep were out of eligibility.
It has been impressive. New offensive line coach Jim Harding is known as one of the best in the business.
