There should be ZERO concern about Matthews' roster spot. He, Gibson, and Landry are the best fits for this offense, and they're all at least capable WR's - with the ability to play the 1, 2, or 3. Given that we want to spread the field and play Wallace at different spots, you'd like to keep all three, and it's not like we'd be dropping better players to keep them on the roster.
McCain is another player who shouldn't be in question. He might not be ready to start, but he's a lot closer to besting guys like Ellerbe and Wheeler than he is to losing his spot to our other scrub LB's. He and Tripp have the most potential of the LB's we have on the roster. If he's not ready, so what? We spend years trying to develop assholes like Daniel Thomas. I'm sure we can keep McCain for at least another season to see how he develops.
