Austin Collie and Wes Welker are basically out of the league due to their reoccurring concussions. Do not know if Monroe had any prior or its his first one, but I'm sure the team isn't rushing into getting him out there. Would like to see a system put in place like the escalating drug suspensions. If you get 1 concussion, a week off, 2-4, two weeks off and so on. These guys that get these and push to get back on the field just to receive another one are not only hurting their own future lives but also their own families. It's terrible to think about.
