I'm not a big fan of Yeldon the RB, but he's a fantastic pass catcher, with the way we use the short pass game with Beasley and McKenzie as running game or to get easy yards, Yeldon should have seen the field more.
Regarding Singletary, we all saw how hard he worked in the off-season, he had a down year no doubt, but I wouldn't toss him to the curb, bring competition via FA, but let's not waste an early round pick on a RB. Also, the OL could have been a lot better at run blocking.
