could be a waste of space for some fantasy rosters
What is the problem here? He's right. If you are in a 10-team league with only 5 bench spots and/or roster restrictions (4 RBs max per team) then sure, I could see dropping them. Chances are you can pick them back up later if something happens because everyone is bound by the same restrictions.If you drafted well, let's say Foster, Lynch, and Ridley are your top 3, and one of these guys was your RB4 and you only have 5 bench spots with 2 starting RBs in your lineup, then why not drop Wells or Williams for some WR or TE depth?
