I say "a" because PT is the main gut in NO and there going to put up points, I think Jenn numbers will be back where they where last years and Gates is Gates
A is the most well rounded package, but I wouldn't overestimate Jennings or Thomas. Jennings has been a bust thus far and it's probably safer to project him as a reasonable but not great starter the rest of the year. And Thomas is high-risk high-reward with both Mike Bell and Reggie Bush around stealing carries.
I've got B at the top as I think Turner is clearly the best player available to you, and I also think Houshmandzadeh is underrated and could put up some nice second-half of the season numbers.
I go B, A, C, D....Gates almost makes A as high....A is really close though as I think Thomas and Jennings will grow as the year goes...I also think you can buy those guys lower than the others
