Just for comparison's sake, here's yahoo's top five:
Steve Smith (Car)
Marvin Harrison
Chad Johnson
Torry Holt
Terrell Owens
I think Chad Johnson's value is questionable now that Housh has emerged as a legitimate #2, and a #1 on most any other team. T.O. is always risky, as he has the possibility to self-destruct at any given time. My five would pretty much be the same, but I'd switch Torry Holt and Marvin. Everyone's sleeping on Andre Johnson this year, but I think Matt Schaub will be better than Carr, thus getting Johnson more balls.
