I'd park Selanne this week. He's missed two straight plus a few more here and there recently, so I'd avoid the risk of him putting up a zero for you this week. It sucks because he can produce for you, but since he can't shake this injury I'd err on the side of caution and leave him on the bench until he heals up. In general in weekly leagues unless it's a stud player I err on the side of caution and bench guys in his situation to avoid taking a zero from that spot.
Your beer mug isn't half-empty, your just half-way to the next refill.....
