To put it differently, is there something fundamentally different between weekly regular season matchups and weekly playoff matchups that necessitates completely different roster management protocols? I don't believe so.
If we get one move per week during the regular season, I think we should have one move per week during the playoffs.
I think that there is something different. The regular season -- much like in the "real" NBA -- is about getting your roster set for the playoffs. Once the playoffs hit, it's all about determining the best team. The NBA recognizes this principle by not allowing teams to sign free agents in the playoffs. Neither the NBA nor fantasy leagues allow trading in the playoffs.
Playoffs are all about dueling to see who has the best team. They're not about seeing who can cycle in the most players to game the system. I'm sure we've all lost fantasy matchups because our opponent decides to cycle, and get a huge games played advantage. That's gaming the system, and simply isn't any fun.
Is one roster move a week really "gaming" the system? I don't buy it.
I don't find the argument that persuasive with a trade deadline three weeks from the start of the postseason. Not a knock - actually I tip my cap again - but the Naturals that tore through the playoffs, Draft Dodgers included, bore little resemblance to the regular season team that was grinding it out for a seventh seed.
And anyway, a large part of fantasy league appeal is working the wire, no? Ok, I'm biased since I like the speculative add more than anybody, Mkgoav excepted, but I still believe 1-2 more roster moves per week is more fun, would add to postseason activity, give eliminated managers something to do, and still a low enough cap to ensure against abuse.
Because bottom line in a 20 team league with 16 man rosters, cycling players can't even really tip the scales the way it can in a more traditional league. And that same league and roster depth makes it much harder to find anyone other than flash in the pans F.A.s during the final weeks of the season.
