I think the question is can you count on Urban to stay healthy for even one game? At least Marlon has shown some durability by playing the entire 2013 season, and he did bulk up to get stronger and tougher. More than likely, they'll give the IR-DTR to Urban and cross their fingers, and if Marlon needs extra time, they'll deactivate him if it's just for a few weeks, but if it's longer, he gets IR'd or cut with the understanding that as soon as a roster spot opens, he gets resigned--maybe for a bit more money than he was previously making, though I can also see Marlon getting the Bajema treatment too this year. Because we are that deep in WRs with 3 who have comparable skillsets to Marlon (Aiken, Butler, and Daniel Brown who I can see on our PS) As for Waller, he's a lot faster than Marlon, so they don't compare. Our coaches seem high on Marlon, so who can say for sure what they're going to do with him, just wish he'd get and stay healthy. Same goes for all our other oft-injured guys. We've got championship caliber talent but much of it can't be counted on for the whole season.
