Why?
Just give the minutes to Jerebko and Mickey.
Why sign a guy who is 30+ and no better than guys we already have?
If the Celts can't get any guys to make a real difference I hope they just roll with young dudes and call it a summer. If it's another summer of stopgap veterans and another year of watching young guys ride the bench while the team fights to a first round exit, I will be peeved, to put it mildly.
