because it bridges the cap between poorly managed teams and contenders, a management team can build and do good for 7-8 years, but a poorly managed team could creep up from behind and win the cup because of the new "level playing field where every team has the chance to win the cup every year"
Every team isn't suppose to be a damn contender every year, that's the whole point of dynasties and building from teh draft so you can be a contender for many years. Parity completely takes away the rewards of having many years of strong drafts (I mean who cares how you draft right, any team can win any year, with a cap players will be waived and signed more than we've ever seen, younger UFA age meaning players will spend less time with one team, etc...)
Parity just isn't good for the support. There needs to be other ways of controlling costs while letting dynasty franchises still exist and giving good drafting a developement the maximum rewards.
I'm the Kings, I've been drafting great for the last 4+ years, I'm hoping in 1-2 years when most of these guys are close to their prime, it's my first year of maybe 5-6-7 years of contention.....ohhh but wait, with the cap and PARITY, I could win the cup next year and then miss teh playoffs the year after, what a reward for drafting so great huh? Thanks parity, thanks salary cap, thanks Gary Bettman and Bob Goodenow (neither of whom has the best interest of THE GAME in their minds)
