Well Floyd will be fine and sit out the rest of preseason. Any injuries to a starting OL would be real bad though. The depth is terrible. This team isnt going anywhere this year and neither will Rivers.
The 2014 draft will be either Clowney...if they suck bad enough to be able to get him or surely a LT. Dunlap and especially Starks are just bandaids. Those should be the only targets in the first round.
