On Saturday, he showed flashes. He led the Blue squad with four catches for 75 yards. His most notable play was a 37 yard over the shoulder pass reception right before halftime that would eventually setup the only score of the spring game. Blue would defeat the Maize 7-0.
However, there is more to learn before he says he's ready to take that next step.
"The most important thing is to try to get in the playbook," Darboh said. "I got to learn all that. The more you learn the playbook, the faster you play and all that. I'm trying to work on the routes. I'm trying to work on a little bit of everything -- so just when fall comes around, I'm the best receiver I can be"
And a big part of Darboh taking his game to the next level is putting in the extra work this off-season.
"A little bit of everything," Darboh said. "Route running, getting off the press, when the ball is up in the air going to get it, and completing plays.
"Also just being a leader. Getting guys out and staying positive to help the team."
He's got the summer to figure it out. Michigan opens up at Utah on Sept. 3.
