Just read the first post and wanted to add my 2 cents in, so apologies if this isn't relevant....but I don't think it's tanking. Tanking is a Big Picture Relevance word. It's a down with the ship type of metaphor that tries to throw away the season for long term gain. Jostling for position is different, would require a different term and IMO, there's nothing wrong with it because it'll probably bite you in the *** as much as it helps you.
