I think it is great that the C's are taking a proactive approach to getting this kid healthy. They don't need him right away, but if he is able to come back 100% healthy, he could be the steal of the draft.
Everyone has been talking about finding replacements for the Big 3 when they start aging...well, Walker has the potential to be that.
I am interested to see what they do for a contract for him now. They are clearly set on taking it slow with him, so I am guessing they will probably do everything they can to get him on a 3 year deal (using part of the MLE or LLE), so they can get extra time to look at him, and also to gain full bird rights.
