for the first three rounds i always go best value. so considering your first three are a rod, bell, and then player X, im going for who ever has the most value in a keeper and point wise. and that is david johnson hands down. he is young, and dynamic. i have gone 3 RB my first three rounds because i dont really care about who is where and who is available and when i think they will be. my first three rounds are all about hitting and hitting hard. after that ill worry about depth and who i can wait on, who is a value where. you can get golden tate in the 6th of redrafts. michael crabtree is about the same. i wouldnt be mad to start rodgers, bell, DJ, crabtree and tate. thats a damn good starting line up. and if you really want to consider scarcity at positions early in the draft so be it, but ill give you an argument as to why you should still go bell DJ. there is no other position in fantasy football harder to consistantly fill than the RB. so to have 2 of the top 3 RBs (maybe even number 1 and 2) i see no way barring any injuries that you will ever regret that. just be smart and pick up probably 3 WRs in a row. you can deal with weak TE play with that kind of team. just dont skimp too much on your backup RB. bell does have a history of injury and not playing full seasons.
