While everyone was all over Anthony Miller (even creeping into the late 1st in some instances), it sure seems Pettis was the true 2nd round gem. I'd rank him just behind DJ Moore in this rookie class at this point. Ridley's value has been decreasing each week as he seems to have contracted a bad case of the drops. Sutton has been doing ok with his starting job after the DT trade, but not as well as Pettis and they were drafted similarly (NFL 2.08 vs. 2.12).
As for redraft next year, it'll be interesting to see if Garcon is back. I assume not, and if that's the case I expect Pettis to be pricey as the de facto WR1 in SF (unless you're drafting with some Goodwin truthers). If he keeps up his current pace, his price will just go up. In his 5 starts since returning from injury, he's grabbed 21 receptions for 350 yards and 4 TDs. If that pace doesn't slow in the last 2 weeks, he's going to be a hot redraft commodity with a healthy JG back at the helm next season.
