I also think it's subjective.....
I took over a sh*tty progressive team a few years ago. Averge sp's NO bullpen, 4 pretty good hitting of's, no 2b and a 0 field good hit 1b. Lacking a 2b, I put an of at the position. He hit @.320 30hr, but had @80 errors. (the player was a B/B, I kept the B/B+ in cf)
I felt playing the best offense gave me the best chance to win. You know, "out score 'em fellas!"Commish called me on it @game 100 saying tanking was not allowed. Gave him a very detailed sitemail, but he felt OOP players were "the devil". He felt I should have played my .180(real avg) hitting 2b fulltime, instead of as the defensive replacement. I thanked him for the honesty and let him know I would not be returning after the season. No hard feelings.
That being said, I have seen others doing strange things, but after going over their rosters, can see why some things are done. And obviously, I have also witnessed gross abuses of the system.... I sitemailed commish on one instance. FWIW
I personally would not join a progressive that won't allow OOP players, I enjoy it more when I can mix and match for the betterment of my team. I traded for ss Bill Russell in one of my progressives, then had the option of drafting Trammell the next draft. Since then, Russell has played 2b and some Lf w/ very good results. Am I tanking, nope, just mixing and matching, putting my best team out there to win...
