The issue is, do you see him as your long term solution, and if not will Glennon starting prevent the Bears from acquiring and giving playing time to the guy you do see as long term (most likely via the draft)? I think there's a non-zero chance he might be. And, if he's not, I don't necessarily think a rookie should just be thrown in, especially if it's a round 2 or later guy. You already qualified it with the worthless "non-zero" designation, why the need to go further with "might".
