Don't jump the gun cowboy, Stewart first time seeing a preseason game was last year meaning he stays hurt during the off-season and is protected because he doesn't get the bulk of the snaps.
he has a bad toe and the first chance he got to prove himself didn't go well since running on a bad toe causes you to run awkwardly. Just saying.
I have to say you sound like you're jumping the gun a bit.. since preseason games don't really prove anything, and he's been stellar every year except this year (for obvious Chud reasons)... While DWill struggled most of last year..
You can't really point to Stewart not being able to handle the load since he has effectively done so every time DWill has went on IR.. and you can't say DWill is a better option since he gets hurt so often.
What we can do is speculate, and feel free to do that as much as you wish. I'm just sayin I would feel fairly confident had we let DWill walk and let Stew/Tolbert run the show and save us money to spend elsewhere..
