Michigan added two needed pieces to its 2013 class with Detroit Cass Tech teammates David Dawson and defensive back Delano Hill. Dawson is the No. 1-ranked guard in the country and recommitted to Michigan while on his official visit.

The additions of the two prospects give the Wolverines five committed prospects along the offensive line and five defensive back commitments as well. Depth is limited for both positions, so it's no surprise that the coaching staff made those groups an emphasis.

Hill and Dawson weren't the only two impressed with Michigan on the big visit weekend, though. Wisconsin commit Marcus Ball (Westerville, Ohio/Westerville South) came away impressed with the Wolverines, as did the Michigan commits on the visit with him. Ball said he now has a lot to think about with his commitment but wants to wait to see who Wisconsin hires before making any decisions.

Offensive lineman Dan Skipper (Arvada, Colo./Ralston Valley) is a Tennessee commit who recently received a Michigan offer and was also on hand for an official visit. Despite landing Dawson, it appears that Michigan would entertain the thought of adding a sixth offensive lineman to the 2013 class. Skipper is still a Tennessee commit, but Michigan might have a shot at flipping the 6-foot-10 lineman as well.

It was a successful weekend for Michigan in gaining two new commitments, but it was also potentially a success for the future of the class as well.
