Posted on Tue, Jul 28, 2009 : 4:36 p.m. Mark Ortmann talks about the Michigan offensive line By Dave Birkett Comments azwolverine Wed, Jul 29, 2009 : 9:58 a.m. It's a HUGE benefit to Michigan to return the entire O line this season. An offensive line needs to work as a unit, which this group finally began to do at the end of last season. With a year of experience and an additional year of conditioning/strength training under their belts, the O line should be an area of strength on the team this year. uminks Tue, Jul 28, 2009 : 6:40 p.m. A QB who can complete passes will really help out the OL...no more stacking the box with 8! I expect a lot more points and a greater time of possession.
