I would say to keep Jennings and Welker but I don't like the fact of keeping 2 WR's so.....(even though you get the 1 point per reception and Welker/Jennings are good for a handful of receptions per game)
I would also say to keep Warner (plus QB's get that .05 per passing yard so you figure 15 points for an average of 300 yards + the TD's but I think other QB's will be available who will put up good #'s as well)......this leaves me to getting the standard RB/WR combo which is good so you can have a good WR/RB and get your other positions later which won't be too much of a droppoff from Warner(QB), Clark (TE), etc....
I would have to agree here with Bazzy and go with Jennings and Grant. Jennings is a beast and will be for years whether it's PPR or not and Grant I think will break out this season and be good to go for a while. GB is just a really "High Powered" offense and it doesn't look like they will slow down anytime soon!
Standard H2H 12 Team 1 Pt PPR, Start 1QB, 2RB, 2WR, 1 FLEX (RB/WR/TE), 1TE, 1K, 1 DEF
