Trade Abdullah for allen

Thinking of upgrading at WR thinking about trading Abdullah for Keenan Allen. My WRs are Odell thielen Cobb and Michael thomas. The league is full PPR with 3 wr 2 rb no flex. My rbs are doug Martin ty Montgomery tevin coleman McFadden Rob Kelley and Aaron Jones. I feel like wr holds way more value then rb in this format and Allen seems like an upgrade any thoughts?

I totally agree with you man I would do it if I could. My next move would then be to package thielen and rob kelly and get a better rb. Just a thought
