Found this in reading through Sharks boards (See below). They feel they dodged a bullet by not getting Cally
I don't want to knock Cally as he squeezes every drop out of talent he has, but this has been my impression as well. I am not a Corsi nut, but it is something to consider.
He is overvalued by fans and media because of what a likeable and hard working guy he is. Sam & Joe rarely get on him even when he fumbles the puck away at the blue line as he is prone to do from time to time.
Callahan is one of those players who will always be overrated and overvalued in NHL circles because he brings grit, leadership, character and other all-important intangibles; he (allegedly) "does the little things that help you win" and "makes an impact that isn't visible on the scoresheet." I'm not saying none of those things matter or even that they're inaccurate descriptors of the hard-nosed, 5'11" right winger's game. But when you're giving up something tangible (draft picks, prospects, roster players, cap space, dollars) I think you had better get something tangible in return. And when it comes to providing tangible value, I'm not sold Callahan comes anywhere near matching the hype.
Consider this: of the 19 skaters who have played at least 20 five-on-five minutes alongside Callahan this season, 16 have a higher Corsi% (meaning the Rangers have done better at controlling play) away from him than with him. That's despite the fact that New York head coach Alain Vigneault has started Callahan in the offensive zone on a whopping 60.7% of his non-neutral 5v5 shifts. This year is far from an anomaly, either; there hasn't been a single season since 2008-09 in which the Rangers have had better territorial results at even-strength with Callahan on the ice than off and, despite his reputation as a defensive warrior, only in 2010-11 did he actually play difficult minutes.
