Also, just the yearly reminder that if you are not stacking and correlating in gpps, you are going about it wrong. IMO one of the better sites and pods for dfs is 4for4. They had a great gpp strategy pod a couple weeks ago, yet again hammered home that all of the winning and top LUs have around 5 players correlating in the lineup. Also, you only need 1 or 2 sub 5% owned guys in your lineup - don't be afraid of the chalk, especially at RB on FD.
Again - 5 correlating players doesn't mean all 5 from the same game. It can be all sorts of correlations. QB/WR + WR from the same game, then WR/TE from another game - stuff like that.
IMO one of their better tips for the first few weeks of gpps was to make sure you are looking at the 2nd tier of games/teams as far as Vegas Totals go. Their point was that Vegas is still good, but early on it might take a couple weeks and statistically it's the teams with the team totals in the 24-26 pt range that surprise. Not that you ignore the other teams, but everybody will be looking at the first tier of KC, Buff, Tenn, GB, SF so maybe eye up something from Minn, Seattle, Atl, Jax, Az, NE for gpps stacks?
