Not yet, that would be a premature move...
Ward is still the talent on his team. Graham will probably get the goal line work... but less touches. Caddy has looked good, but I'm willing to bet he goes down again.
Davis is still unproven in a regular season game. I know it's nice to take risks and pick up a 'possible' breakout star, but it's a huge question mark right now.
Your RB's look good - LOL, I have the same 3 in my PPR league. Good drafting there!
