Colorado head football coach Mike MacIntyre has often said that when offensive lineman Isaac Miller is healthy, he has the ability to be special.
Unfortunately for CU and the Silver Creek High School graduate, he's not healthy and there's concern about whether he'll ever be healthy enough to help the Buffaloes on the football field.
In previewing spring practice — which begins Friday — MacIntyre said Thursday that Miller won't practice this spring, as he continues to deal with knee problems.
Whether Miller, who started six games last year at right tackle, will be ready for fall remains to be seen.
