I think this is a good trade for you but I doubt he accepts it. This season Hicks is better than AJ, McFadden has shown himself to be a top 5 FF RB this year (even with missing 2 games he's right around the #5/6 RB in most scoring formats with just 5 games played) and Gates is battling an injury which decreases his value. Try it and keep you fingers crossed.
This aint a NYC auto garage, if it aint broke, dont fix it.
