One day later, not only did he make it to Michigan, he actually had a good time. And a lot that has to do with U-M coach Jim Harbaugh.
"I enjoyed it a lot," he said of the visit. "I got to talk to some of the coaching staff, but not all of the defensive coaches were there. But I got to hang out with Coach Harbaugh, eat dinner with him and talk to him, and build that relationship right before I commit [June 7].
"He was extremely energetic," he said of Harbaugh. "So imagine what he is like at practice? He seemed like a cool coach to be around. I mean, he came from the NFL. Who wouldn't want to get coached from someone who has been where they want to be? You know what I mean?"
Now that he made it up to Michigan for a visit, where do the Wolverines stand in his recruitment?
As far as what he's looking for in program, Robertson says coaching is going to play a huge role in his decision.
"It's going to be based on my relationship I have with the coaches," he said on his deciding factor. "Life after college. Who I feel will help me develop to be a player who can play in the NFL someday. That's my ultimate goal is to play in the league. If that all fails, I want something to fall back on. My education, no one can take that from me."
And if possible, Robertson says he would like to make another trip to U-M before his commitment, this time with a special guest.
"I want to have my mom come down there one time to see [Michigan]," he said.
