Staley for Bettis
Bettis doesn't look like he can carry the work load for PIT anymore. He will still get his touches, but I think the BUS is running low on gas. Staley is splitting time with Levens/Westbrook. so both fantasy numbers will go down, but at least Duce gets receptions.
Staley will have better numbers
LT for George
If the foot is okay I think George will put up better numbers than LT
Rice for Owens
you really improve here. Rice is good and will probably be the greatest receiver in NFL history, but Owens is the man now. The 49ers have started out slow, but he will get his numbers and the 49ers will get back on track.
I would do this trade only if the foot injury isn't going to hamper George all season. Sit on the trade until after this weekend and see how Eddie does. I think this would improve your team.
