Kesler's shot just isn't good enough at this point to warrant spending assets to get him a playmaker.
I would strongly disagree with that notion.
Granted, Kesler's shot isn't half as great as he seems to think it is, but the real issue is in how he is intent on using it. He wants to use his shot like a winger now...so bet it, let him be a winger and use it. He does have a
good snap shot though, he just consistently skates his way with the puck into situations where he can't use it effectively.
But the real value in a playmaking center on Kesler's line, would be in allowing him to do the things he seems most interested in doing these days, more than just the shooting. Getting in aggressively on the forecheck, taking shots, battling in the corners, and above all else, parking himself around the net and working the crease and slot area to tip pucks, bang away at rebounds, create space for linemates, etc. The sort of things he does so well on PP. Get somebody on that line at center who can
competently control play and distribute the puck, and you not only make Kesler more effective in what it is he is trying to do...you also reach a point where Kesler makes his linemates more effective again, by playing that valuable 'power winger' role, creating space, sniping shots, and putting away the garbage around the net.
