too expensive and eliminates all available cap space for more critical upgrades. look at teams that have won cups and the pieces they added at the deadline. i don't remember a single blockbuster deadline addition being part of a cup winner. people overlook the human side and locker room impact on those deals...hard to bring a superstar who's been in one place his whole career, worn the c there where he played a huge role in establishing that culture...and expect him to immediately and simultaneously immerse himself in a new group/adjust to taking a secondary leadership role/deal with all the stuff that comes with living in a new place and working out his family life/find his role on the ice with the team which will almost certainly mean disrupting something that didn't need to be disrupted like pp1 etc. it's not a video game where you pick up a 93 overall player and he plays like a 93 overall player and it has no impact on anyone else on the team. if they had a true need he fit and the idea was he'd be signed, sure. he is not what they need though and he can't be resigned. the need is an upgrade at rw in the top 6, but in the form of a complementary skillset that fits the other 2 players, not one of the biggest names in the league that completely alters the dynamics of the line and team. he makes no sense from an asset management, roster management, or locker room dynamics perspective. the only place it makes sense is a video game.
it has nothing to do with stamkos and not in any way saying anything negative about him. he's a guy any team in the league would want, but you can't add him as a deadline piece to a team that expects to be a contender. that's a guy you need to have from the beginning of the season to have any chance of him adjusting to the team and finding his role where you could actually get the best of him. hell many big names who switch teams struggle their entire first season in a new place....for every matthew tkachuk or panarin there's a huberdeau/meier/gaudreau/dubois/trouba etc. there's simply no reason the rangers should even consider it, and quite frankly, unless stamkos wants out neither should the lightning.
