It's just that you made 16 PP points seem like a huge hole to be filled. I mean, it's "a lot" but if 4 other people find a way to chip in a couple extra, a guy "replaces" Radulov with a ~10 PP point season. I'd argue further that a difference of 6 points at any one position can be compensated for over the course of the year purely with coaching/systems. And that's without getting into opportunity and natural variation of contribution as special teams personnel change through the year.
Pretty useless to dwell too much on. For me it's more about losing his ability to generate pressure/chances, make plays in tight places, and occasionally make something out of nothing on sheer willpower. Points aren't quite everything when it comes to Radulov, and that's why it's sort of too bad he's not still part of the mix. At the same time, 5 years... at close to top dollar for those numbers... I dunno...
Sort of like Markov. Would be better if he was still part of the mix, but I'm not surprised that middle ground couldn't be found between asking him to stick around as a 2nd/3rd pairing guy and getting paid like one, and what he probably offered to Bergevin as a $5+ million 1st pairing guy who would arguably still walk onto the 1st pairing tomorrow. Not there was an opportunity for middle ground to be found, mind you, if Bergevin rejected his first offer and he never came back with a lower 2nd one.
