There's just too many good RB's now, it's pointless to spend a large amount of coins on one. HW Campbell, HW Sanders, HW Peterson, HW Walker, HW Williams, HW McGahee, HW Allen, HW Griffin, HW George, Cover Williams, Cover Alexander, Cover McFadden, Cover Ingram, Leader Ball, Leader Gerhart, Elite Smith, and Elite Richardson are pretty close in ratings, it's all about preference. None of them besides Campbell, Williams, and Sanders are really worth any more than the others. Some are more rare so they carry higher prices, but you can't go wrong with any of these.
