#1 vs. #8 and 2 vs. 7 etc. is not a rigged system.
It would still have been the same #1-#8 and #2-#7 matchups if they went that way. The 3-6 and 4-5 matchups would have been different - only change would be Rangers and Lightning.
Chaos still ensures because of the Florida first round upset.
Florida vs Boston
Toronto vs Rangers
Carolina vs Islanders
Devils vs Lightning
At the end of the day I prefer the 1-8, 2-7 system, but its still hockey. Upsets happen quite often in a 7 game hockey series, no matter how you set up the bracket.
