To the chase: three solid sources, one of them Buckeye Planet's unionfutura, indicate that MI QB Devin Gardner has moved up his announcement date to Monday. He plans on attending the Michigan junior day festivities this Friday; you can draw your own conclusions from that. Also, both sources indicate it's looking very, very good for M. BP has already labeled him a Michigan verbal. Party hats are likely.
Gardner would be a big pickup. Today's weird Rivals 100—which does not include Gardner or Ricardo Miller—aside, Gardner is widely regarded as one of two players vying to be the state's top prospect. (Southeastern LB/DE Will Gholston is the other.) Gardner was Michigan's top QB priority this year and has offers on the table from Notre Dame, LSU, Michigan State, and others.
Here's a TomVH interview with Gardner from last year for more detail, and some camp highlights:
He is a fantastic prospect athletically and looks great on the hoof. Is the ideal fit for the spread offense and a short controlled passing game that plays off his threat as a runner. He is a gifted player with his legs and can improvise and create positive plays when things break down. Initial quickness and ability to take off out of the pocket is excellent.… However, for all his athleticism and arm strength, Gardner's mechanics need a lot of work. Fortunately he is blessed with height because he has a very low release point and is a side-arm passer that cradles the ball and tends to push it in his delivery. … Like Vince Young there is probably only so much you can do with his throwing mechanics, but lots that can be done with his feet to help him become more consistent. He is green, but talented.
