Yeah, big difference between tanking and sucking. When you're looking for subtle (or not-so-subtle) ways to take natural sucking to a higher level, that's true tanking.
What some people don't realize is that players and coaches on bad teams will still be looking for jobs in the seasons to come...they want to show potential new employers that they have something to offer. Obviously a GM or team president can make a deal with a coach behind the scenes and say "Look, we know it's going to be rough here over the next 2-3 years, but we know once we get you the pieces, you'll do the job.", but what motivation do players like Elias and Jagr have to tank? Or for that matter, guys like Schneider, Henrique and Cammalleri? It's easy for us to say "Tank and get some prospects," but losing for the sake of losing goes against the inherently competitive nature found within most professional athletes...and I think a lot of guys on the current roster wouldn't be too happy if Lou ever made some of the moves you allude to (which would be an obvious attempt to lose games). Some will say "Well, these guys suck anyway, and a lot of them won't be here much longer, so who are they to be angry about anything? If they were any good, they wouldn't be in this mess to begin with." But even if it's not showing up in the results, guys still have pride...I don't think it's easy for them to lose, especially when it's for a future that many of them won't be around to benefit from (and that's assuming the losing will pay dividends down the line).
lets get one thing straight.. in pro sports, players and coaches DONT TANK! Period! tanking (probably a bad name to call it) is an ownership / GM decision regarding personell and their future. its taking well planned action without regard to the current here and now, for the improvement or potential improvement long term
its not blowing up the team, we need to field a team next year
its not intentionally losing, that doesnt happen
this season is over! wins are not the most important thing right now
the highest draft pick is probably top 3 of important things
