FF: I'm on the clock and need help with my 1st pick (7th overall)

[CarlSpackler]

I'm the 7th pick in a 16 team draft. League starts 1 qb, 2 rb, 3 wr/te, 1 k, 1 defense. Standard scoring - 6pts for TD passing, receiving, or rushing. 1 pt per 10 yards rush/receiving, and 1 pt per 20 yards passing. Turnovers -2. The following players have been picked in the first round in order:

Tomlinson
Alexander
James
McGahee
Manning

The 6th pick is on the clock and I'm next. If Priest is still available, I'm obviously going to take him. If this guy before me takes him, who do I take? I'm trying to decide between J. Lewis-rb, Randy Moss-wr, and D. McAllister-rb. Who do you think is the best choice?
