Never too early, was looking at playoff matchups starting when the bye weeks started to look for potential trade targets.
BAL is mentioned with a favorable schedule weeks 14-16 with two key finishing games -- @ PIT, @ CLE, IND.
Others teams with at least two favorable match ups I like for targeting offensive skill players are:
BUF: IND, MIA, @NE (all three match ups at this point look solid)
DEN: NYJ, @IND, @WAS (a little iffy as Denver needs to re-settle offensively after their QB change, and NYJ can sometimes bring pass pressure)
DET: @TB, CHI, @CIN (I'm wary of Cincy as their D can be good, but TB's D looks to be a mess and CHI's hasn't been fearsome)
Only other might be TEN, who faces @ARI, @SF, LAR. Rams can play really tough D so that's not a great matchup, but the 9ers is, and ARI has been up and down on D this year so depending on their trajectory these next weeks, ARI may become a D that can be targeted.
