Only note I would have on your spot on post, Steve, is that I normally would multiply the effects of CP on a player by 2/3, since they typically play 2 out of every 3 matches while OTF adds to your stats 3/3 matches.
Agree that the positional flexibility is a key benefit of MPPs. I use SDs to easily switch to having 6 defenders when moving to a stall, for example.
But I think the benefit I tend to value more is the shooting boost - having a MF that shoots like a FW or a DF that shoots like a MF. Probably only leads to a couple more goals per season at best, but that's not half bad!
Now, my vaguely related big idea for OLMEC in the 2020s...what about wingbacks? A MPP position that can play WG or DF with no negative effect. I'll admit this would benefit MOT's playstyle greatly, but it would be an interesting twist to bring WGs into the MPP fold that everybody could take advantage of.
Looks like you forgot a banker in the prediction league. Hope you see this in time!
If my tabulation is correct, this is the 6th season we've had the superstar draw, so it is worth a look at how the random draws have shaken out:
Won 3 times:
ARB, COW, PT
Won 2 times:
AI, FAL, FRA, STE, EST, ELG, RR
Won 1 time:
CEL, BRE, ROS, INV, EDI, SRA, QOS, CB, BER, DEE, EF, SM, ALB
Never won:
ABE, ALO, ANN, AYR, CLY, COV, DEV, DUM, DUU, DFA, FOR, GM, HAM, HEA, HIB, KIL, LIV, MON, MOT, NAI, PET, QP, RAN, STJ, STI
Not too surprising of a distribution for random draws over 6 seasons, but there are some interesting details:
