This seems to be a consensus. I respectfully disagree with most of you.
Regardless of rounde drafted, the skill positions have delivered a nice return on investment in rookie RB's, TE's and WR's in recent years. College players are being coached in the pro style offenses and formations, and the learning curve is not as steep. Last year, Mike Williams was a 4th round rookie, and his teammate UDFA, L. Blount made a serious 2nd half run. 4th rounder Jacoby Ford came on in the second half as well. The Patriots hit big with both their two rookie TE's.
I will be tempering any expectations in the early season, as the defenses will likely dominate the offenses till they find their rhythm. But I will be expecting the rooks to soon find their footing. And it wouldn't surprise to see someone other than Green and Jones being fantasy ROY.
Rookies are going to be a good stash and hold for a few weeks. They will be excellent buy lows. While I agree that they won't produce as great a cumlative numbers, they will still be important players to have on your roster as the playoffs approach.
Bottom line is I am not going to downgrade a rookie by the "lockout" factor, even if the season is shortened. If I like what I see in preseason, however short that is, I am drafting accordingly. Whatever FF points I lose out on earlier in the season can be made up and then some when the games take on more meaning.
