As everyone knows former Ohio State commit Kyle Kalis is visiting Michigan this weekend. He told me that he's very excited for the trip, however I wouldn't expect a commitment this weekend from him. He does have a lot of interest in Michigan, but he decided that he also wants to visit Alabama and Miami first. That isn't 100%, but that's the plan going into the visit. I always say that visits can change things, but this is the plan as of now.
Kyle is aware of the situation Michigan is in with the recruiting class and how many spots are left open. If no decision is made this weekend don't be surprised if any of the other linemen Michigan was in good shape with end up pushing their decisions back or going elsewhere. I believe that they would wait for Kalis to make his decision, rather than letting it fill up.
There are guys like Blake Bars and Eric Olson deciding in the near future. Bars is deciding within a week, as I reported in his interview earlier. If the coaches want three more linemen and if Blake Bars were to choose Michigan they could potentially still be fine. That would probably leave spots reserved to wait for Jordan Diamond and Kyle Kalis. If they want to take three more. We'll see how it plays out, but do note that Kalis has a lot of interest in Michigan.
