With more and more teams running the ball to the left, knowing that many teams put a pass rush specialist there who's weak against the run (can you say Osi?), it seems to me that JPP is the prototype for Right DE now. They've got to become three down players who are good against the run. The LB on that side needs to be a disciplined guy with good speed who's capable to playing against Shanahan's option system. The right side of the defense can't be a pass rush only zone any more, especially with the RGIII's, Russells' and Kapernicks that are playing QB now.
BTW- there goes Osi's value in free agency too.
