Eh, I'm still of the belief that Kesler requested to be moved silently, but management sort of dicked him around just like with Luongo, likely waiting for the perfect deal (read as: overpayment) that would never come. After a season or two, Kesler finally decided to make it public even if it reflected poorly on him, but with the intention of creating some urgency with management to move him.
Overall, I think he devoted his best years to us and will probably have some nagging lifelong injuries based on how hard he played for us. In that regard, no hard feelings on him moving. We don't "own" him, we don't owe him, and he doesn't owe us either.
