Need Input. Pick 2 (PPR): Antonio Brown, Givens, or Green-Ellis

A. Brown vs. SD
- con: slow start since coming off injury
- pro: gets Big Ben back (but how effective will Ben be?)

C. Givens vs BUF
- pro: b/c of key injuries, has emerged as Bradford's #1 guy and in a big way (27 targets in last 3 gms)
- con: given his inexperience and now known threat to opposing D's, can he keep up this high level of productivity?

Green-Elis vs DAL
- con: tough matchup. DAL Def is in the top tier of my league in giving up least points to RB's (although last 3 games they have been torched by Richardson, Morris, and Bryce Brown)
- con: receptions are few and far between.
- pro: has really picked things up in the 2nd half of season. 100+ rushing yds in each of last 3 games (against weak opponents though)

I generally prefer starting a WR at flex in PPR leagues. But given my limited options due to other injuries, my gut is leaning towards starting BGE at flex and Givens as my second WR.

Thoughts? TIA!
