I have a big game this weekend and i need help deciding the best combo for my starting roster.

i have 2 rb and 2 wr/rb slots in the starting roster, these are my RB/WR that are candidates for the spots:

Thomas Jones, Leon Washington, Brian Westbrook, Donald Brown, Larry Johnson, Correll Buckhalter, and T.J. Houshmandzadeh

Houz is the only receiver on my bench, the three starters are moss, colston, and jennings. but i dont know if he would be better at a wr/rb slot than a rb. Please let me know what 4 out of those listed players would be most effective this weekend.
