In the comments below the lines. Rooney has a year left. If Barron forces his way on in camp, that's great. I'm all for it. I won't cry about Rooney not being a regular. If Barron can't force the issue in camp than he only has a year to wait. Spot is his to inherit.
I like Barron, but it's not exactly a MUST that he be on this roster this year. If he shows that it is a must in camp, that's awesome. But if not, him getting ~30 games as the first injury call up and waiting for Rooney's deal to expire isn't the end of the world.
