If he is on my current roster he goes on the dl. If he is a keeper option, I DO NOT keep him unless I have terrible options. As far as drafting...In 16 mocks I haven't drafted him one single time. However, if you've drafted and he's on the wire...by all means pick him up if you have dl room, or bench space.
I'm in a 14 team league with 10 keepers and I'm not keeping him. Decided to keep Morrison over him. Keep him at your own risk, I don't believe in keeping someone who is a complette question mark and you may get nothing from.
