Good point, I'm switching him back to a RB just for tonight so the lower fatigue setting doesn't impact my WR's.

In that case, you should probably change his backup to RB also. Otherwise the starter will play one play for every 10 of the backup.

excited to see who wins tonight anyway it's a great matchup. chicago was 1-15 last year and now they are in the league champ game

Yeah, I had thought the same thing and made the switch. My 3 RB's will get a pretty even number of snaps.

Me to, I didn't expect to win either of my playoff games, but here I am so might as well win another one. Chicago has had a great season and their rookie WR has put up ridiculous numbers.

Wait... WR lining up as RB will react to fatigue settings from WR?

Fatigue settings control substitutions based on the depth chart. If he's lined up as an RB, the backs setting will control. If he's lined up as a WR, the receivers setting will control. If he's lined up as both, it's based on the fatigue of the players in the depth chart at both positions compared to each setting, to determine where he's needed for a particular play. If he's the top of the depth chart at more than one position, it's random until his fatigue reaches a setting for one position. The position he suits up at can affect weight and thus indirectly affect fatigue, but it doesn't directly interact with the positional fatigue settings.
