I think Harrison is the answer and I think we have a good shot at keeping him but I passed on voting for him because of the uncertainty.
I think Farmer might be the best player but we won't hear nearly as much about him because you mainly hear about OLinemen when they screw up. I also think Walton will be really good but we have quite a few good, young LBs that he'll have trouble getting on the field for awhile.
I went with "Other" and am putting in a vote for Jariah Tolbert. If Harrison stays, Tolbert won't get as many chances. But I see him being a great Red Zone weapon - just throw it up there and let the 6-3 guy who can jump and aggressively goes after the ball to catch it with his hands go get it.
