I'm opening myself up to be pelted with rotten vegetables, but I think there's a fine line between tanking and rebuilding, and people are too quick to tag guys with the tanking scarlet letter. While the scenario presented by MikeT23 in his original post is extreme, I don't see a problem with a new owner taking over a team and overhauling his roster. It's part of the learning process and it's more fun to build a winner from scratch. This is a difficult game to learn; I considered myself a seasoned whatif player and it took me a few HBD seasons to fully get a grip on what ratings mattered, how projections worked, what salary moves made sense, etc. I find it way more detrimental to a league to have a newbie sign a guy like Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Vin Rincon
to a ridiculous long term deal and then bail on the franchise. At least "tanking" owners hold onto their teams long term, have to eventually pay their guys, and end up being good owners.
It doesn't make sense to lose for 7 seasons for the purpose of a better franchise down the road, but i don't see a problem with entering a league and setting a target season based on your first draft (3-4 seasons).
