well PL wouldn't interfere with anyones training, and scrimmages could only be done with people out of the cup.
The idea behind the PL was more so that it had minimal effect on a user's normal game efforts. a bit like having really low salary players used, it has minimal impact on the actual league/training of the user's real team. I wouldnt ask people to give up their training minutes and GS management minutes during scrimages, just for research.
i did just think of something though - if you were constantly trading players to use - even if they are poor salary, it would effect the team's survey and % of sale for other players.
so it might have to be a 'constant lineup' for the length of the PL - which then managing GS becomes an issue. but I guess you would address that as it comes.
even if it was say, 4 teams. home and away - so thats 8 games. 8 weeks. say you had, 5 players to use, so thats roughly $10k-$15k per week salary. so worst case scenario $15k x 8 weeks = $120k plus purchase costs ($5k) = $125k)
so the initial outlay is nothing. and potentially might be using scrubs that people already have.
And so in season 1, rnd 1, all teams would play LI V 2-3 zone for example. With each team having a different level of player at each position. Team 1 might have everyone who is a forward have atrocious SB. Team 2, Inept, team 3, mediocre, Team 4 respectable.
and generally all other stats across the board would be the same. So essentially you would see the same kind of offence play against a slightly different defensive setup, based on SB.
Then just do the same LI V 2-3 zone for the away game, such that you can see how much of a factor HCA played in it.
and then for the remaining two rounds, you could play, LI V M2M. and see the results that come out of that.
im so just talking out loud here.
