Earlier this week, the folks in the Colorado sports information department had some fun with a fictitious Michigan depth chart in advance of the team's game Saturday,

The depth chart included names like Danny DeVito, Elmer Fudd, Kareem Abdul-Jabbar, Clark W. Griswold, Austin Powers, Vito Corleone, Happy Gilmore and more.

Michigan doesn't do a depth chart, so Colorado made a fake one for the week. Nice work by SID Dave Plati! pic.twitter.com/EQr0LloHrB — Kevin Kugler (@kevinkugler) September 13, 2016

Michigan coach Jim Harbaugh wasn't amused. He was asked about it on 97.1-FM in Detroit on Thursday, via MLive..

"In our preparation for Colorado we've had a hard time working humor into the preparations," Harbaugh said. "They're a very good football team."

"I saw the depth chart," he said. "I was trying to imagine how many people sat around and how many hours they worked on that. We've just found, I mean, when it comes to the depth chart -- modern technology seems to have made the depth chart an out-dated task by about 20 years. We've found studying last week's film of the opponent is the most accurate way of determining another team's depth chart.

"There's so much written about the team that's on the Internet. For those of us who can or do watch the games -- they're all on television now as well -- we just felt like modern technology was the most accurate way of knowing what the opponent's depth chart is by looking at the previous week's film. And not relying on another PR director's assessment of what the depth chart is."

The No. 4 Wolverines (2-0) faces Colorado at 2:30 p.m. Saturday.

Wilton Speight threw two of his four touchdown passes to Jake Butt and Khalid Hill ran for two scores, helping Michigan rout Central Florida 51-14 last week.

The Wolverines (2-0) have won their first two games by a combined total of 97 points.
