This is a great thread
*Not an advertisement* Since 2001, I have used MFL for our league hosting(s).
The reason we pay for the site is because the scoring can really be dialed in (by Me).
For all the leagues I commish or co-commish, Kick and Punt return yardage is scored for all positions, except PK because they are not used in any of my leagues.
All the leagues I'm part of use IDP's. So, for the last several years I have been keeping track of Rookie CB's. Sometimes they come out of the box starting on D and playing special teams. Others just play teams. That doesn't make them useless because players get hurt and they get forced into the lineup. Week 10 is when you really want to start looking at those dudes.
WR's were the other choice. Most of the players from this position are the small gadget types. These players are not usable unless a league has a KR spot.
RB's will be used, but they will be the type that can't handle more than 150/175 attempts in a season. Those players are worthless unless a league has KR spot in the starting lineup.
My first thesis is that the usage will remain the same for WR/CB. RB will probably dwindle, just because of scarcity.
Lol, very bold prediction there, considering that the most drafted players were WR/CB this year.
I'll be keeping up. Thanks
