I think Foster is going to be a top 3 RB at the end of the season but megaton will be the clear number 1 as that Det defence is still terrible leading to a lot of shootouts and comebacks. PPR is a boon for Megatron over Foster.
That being said, it does look like Ridley is going to be a unreliable back with game plans in NE always changing and that new rookie stealing goal line carries.
With your WR's I think this is an overall upgrade for ya. I'd take it for sure!
