But in the wake of Michigan’s loss to Penn State and overall struggles, Howard had a tough evaluation of head coach Jim Harbaugh.In a recent appearance on ESPN’s Get Up!, the former Heisman Trophy winner and Super Bowl MVP called the Michigan football program “behind schedule based upon expectations.”Howard explained that Michigan should have been in contention for a national title by the fourth year of Harbaugh’s tenure. But it’s now Harbaugh’s fifth year and they are not quite ready to compete for one.Via 247Sports: “I think the state of the program right now is behind schedule based upon expectations,” Howard said. “Meaning, when they went out to get Jim Harbaugh, that was a big get. Oh man, we got the best coach out there… Everyone expected Michigan to compete for a national championship, probably by year four. Now, we’re in year five and Michigan has yet to compete for a conference championship. So at this point, I think it’s safe to say they’re behind schedule.”Howard went on to call the state of things that Michigan “indefensible” when it comes to Harbaugh’s record in big games.It’s tough to argue with the assessment.When Harbaugh took over in 2015 after a stellar tenure with the San Francisco 49ers, and an even more successful spell at Stanford before that, it was believed he’d return Michigan to the national title picture.But while Harbaugh’s record is the best at Michigan since the late-1990s, his inability to beat Ohio State or win a major bowl game has been a frequent criticism.And when Desmond Howard starts expressing his doubts, you know that there’s serious trouble brewing in Ann Arbor.
