fwiw I prefer to start with no rookie WRs or TEs as they usually tend to take a year or two to start performing. On the other hand, rookie RBs can impact from the start so I'm happy to load up on them.
atm I have:
QB - Mahones, Mayfield + Murray
RB - McCaffrey, Ingram + Jacobs, Montgomery, Sanders and Ballage
WR - Adams, Hill, Hopkins,OBJ + DJ Moore, Pettis, M V-S and Kirk
TEs- Henry, Walker and McDonald
K - Pineiro + Wright
DST - NY Giants + Cincinatti
