First of all, I NEVER suggested that the Sens (or any team) does or did in fact purposely lose. But since Evan was suggesting that the Sens had nothing to gain or lose after they clinched a playoff spot, they would lose since there was NO motivation to try.
BUT, there actually was something to play for.
1) Even though they were guaranteed a spot in the playoffs, they still could move up or down. They lost 3 games that, had they won. would have likely moved them as high as 6th, but they lost, and finished 8th.
2) There seems to be some suggestions that the Sens stood to gain and benefit from losing those three games to avoid playing Boston - the reigning champions and a team they have not had much success against.
3) IF the Sens did lose on purpose, it seems to be that they did so to avoid playing Boston and to play New York, a team they have had better success against.
4) If you accept that it is in a teams best interest to strategically lose - that is, it is to their advantage to lose for the purpose of gaining something - then you have to accept that a non-playoff team also stands to benefit from losing to gain an advantage, which in this case is a higher draft pick.
5) This idea of strategically losing does not entail purposely throwing the entire season. It does however suggest that once there is either nothing left to stand benefitting from (i.e. a playoff spot, or a desired match-up) that it might be in a team's best interests to lose.
6) While I acknowledge that some teams have continually finished in the bottom more than others have, it doesn't mean that they "tanked" or that they want to lose, or that they encourage and adopt a losing culture.
7) There are exceptions to your claim, since Florida has turned around consecutive losing seasons under new management and a roster overhaul. As well, there have been 2 Stanley Cup Champions in recent years that were at one time not too long ago a bottom team for many years.
