I dunno, while Cobbo had some nice solid kick returns, he didn't look like he wanted to be there. Felt like he was doing what the coach/trainers told him to do (run hard), but his heart wasn't in it. Him jogging in the background when Sailor was looking for support was concerning. I think he may be more of a liability (on the field) at this point.
Also on Mozer, he can pass really well (those long passes seem like something we should try to take advantage of more), and he's got some nice deception around the ruck, but I think he still has a way to go before we put too much pressure on him with comparisons I.e. especially with his running and kicking game (he might just be keeping it simple for now).
