IMO, Beasley and Singletary are playmakers.
I'll probably get slammed for this, but I don't see Singletary as an RB1. I like his game, and like what he brings, but I see him more as a 1A/1B guy. I don't think that he possesses breakaway speed, his hands are a little suspect, and I did see him miss a number of holes this year. I think that a Kamara-lite type of player would do wonders for the offense.
