..Passing game is the functional equivalent of a running game. Until it isn't.
I wouldn't ride him to this extent. Great values are to be found in RBs because the position is undervalued. I'd get a tough physical runner or two and build the line.
If they are going to continue on this year's path, they need to build the line and get more receivers.
In any case, build the line.
I don't think RB's are really undervalued. You can find them without spending high draft picks or lots of cap dollars, but they aren't really undervalued. Most of them are fairly fungible and the few that aren't that would have been fairly wasted behind the line this year. The interior line hasn't been very good in the running game outside of playing the lol Colts for a couple of years now, hopefully the young guys develop there. Tackle is, to me, the biggest need. Cannon and Fleming aren't really NFL caliber players and Solder and Vollmer aren't going to be around forever. More toys at the skill positions would be nice, but they have enough to win with even average tackle performance.
