I have Cobb and tried trading to get Moore, so I like both guys. Both games will be shootouts. I think it comes down to this, Cobb is more explosive and could go off for 2 td's, whereas Moore is safer due to less competition on team to get 7-9 catches, 100 yards, and TD. If you have a tough matchup in your league, you go for the Cobb, if not, go Moore.
