Fantasy football 3?

Question

is this a good running back system

LT and McFadden and i got fred taylor as back up

Answer 1

Only if McFadden turns out to be as good as AP, which is unlikely, so it's not that good.

Answer 2

Not really unless it's a super deep league.  Rookies are always risky and McFadden has competition anyway.  Taylor is a very good #3, but only if you have a better #2 b/u.
