Yea i'm slightly wary of the ben tate/foster dynamic that could turn into a 50/50 split any day they're both very good. as for movable assets you've got some good depth which should net you something of value.
Ideas if you get lucky and Loyd has a good game I would jump on that value and move him right away I'm personally not really a fan of too many pats players (besides brady) the pats just take advantage of match ups so much that you end up with a boom or bust player and personally i value consistancy. Not to mention how many mouths they have to feed there.
If you were to package Lloyd with a running back you should be able to get a decent qb sproles specifically has a ton of value in an ppr league so you may be able to get something good with them. the problem is the top 5 qbs are pretty far above the rest of the crowd, and will be difficult to get from their owners. The 6-10 aren't too far ahead of what you have now so it's going to be difficult to find a trade that's worth it for you. This early in the season there's no such thing as too much depth. If you wait for an injury a very desperate team may come to you later that will put you in a great spot for a good value trade.
