I don't think anyone's sad that Kovalchuk's contract isn't on our books until the year 3000. Plus, cap recapture and all that. Lou's final gift was getting us out of that contract.
Also, you're incredibly misinformed. Not entirely surprising given your... well, I don't want to make this personal and have a mod jump down my throat so I'll just leave it at that.
Not to speak on behalf of the other dude, but I don't think there's much salt as far as him not coming back to the Devils.
No Devils fan with a brain wanted Kovalchuk back now. We've clearly got something working - why risk infecting the locker room with this cancer when his best hockey is clearly behind him.
He owns a house in NJ, his wife wants to be close to NYC, and the Rags undoubtedly offered more money than anyone else with half a brain would be willing to.
Rags are trash and have a ton of cap space - why not sign a past-his-prime star? Reminds me of the good old days.
The wrong move is adding talent to keep yourself out of the top-5 in the draft. Dip your toes in the "pool of mediocrity", get your young talent, then get out.
Rags are going to do a great job hovering right around 10 O/A with Kovy while Hank is still around, which is just fantastic.
In short - I love this move. Let him infect your young guys with his ego, while keeping you just talented enough to stay out of a good draft pick.
