Are Ahman green, Ryan grant and thomas jones overated?

If you havent guessed it yet they all have 1 thing in common.....BOOM..it's favre(madden) .these people have great careers with farve but take him out and i see nothing...I ume maybe its because teams play alot of p D against favre so it gives runningbacks alot of open space. ahman green was solid his whole career but when he left favre he has been horrible on the texans even before injury.Slaton didnt get given the startin he took it!! and this year ryan grant has been about as useful as a Can opener in a can. or a nuclear hand grenade. Thomas jones is doing great dis year. and bears should have never released him. but he has never done Dis good, even if he was on steroids i thought i'd never see a day where he would start in a pro bowl....are they overrated?
