How true to life do you find these mocks? When I started playing online poker a hundred years ago, I played a lot of free games at first, thinking it would help me when I started playing for real. Instead, I found that people made all kinds of crazy moves they wouldn't in cash games. Well, I guess we'll see. Hopefully, people are taking them seriously.
Been mocking at FFC for a few years. You'll always find the occasional idiot who thinks it's funny to take John Skelton or Tim Tebow at 1.3, but in general they are pretty solid.
The users don't always go with super hot trends. The offseason before Foster's breakout, I was consistently getting him in the 6th round. When I drafted in both my leagues, he didn't make it past the 4th.
Finally, you'll find that after the 7th round, more than a few folks will drop off. Makes it tough to figure out if your sleepers are on the general public's radar. But I've seen similar or worse elsewhere.
As to the original question, I've always played in 6 point passing TD leagues, and have always stuck to the RB first mentality.
While there is no additional advantage to rushing TDs from Vick and Newton, a TD is a TD. The ADP for Vick on FFC, for example, is at 4.01 in 12 team standard. Even in 4 point TD passing leagues he's not flying off the board yet.
On the other hand the RBs you'll be looking at with the 20th pick (assuming a few more QBs go early) are Charles, Peterson (with PUP still likely), SJax, Lynch and FJax.
So for your haul in the first 2 rounds, the real question is would you rather end up with Rodgers+one of those 5 backs, or Mathews+Vick/Romo/Peyton?
Worst case, if there is a QB run in the 1st 19 picks that takes 11 QBs off the board, you will theoretically have a top 5 back and a top 4 WR in your 1st 2 picks... plus the ability to wait until at least the 7th to get a QB.
