I think Carle is/was a good, durable, utility D-man who could play in all situations but not really excel in any of them. Given the injuries and such it would have been a nice luxury to have retained his services, but I'm happy it wasn't the Flyers paying him that deal.
One thing puzzles me though. One of the things his proponents claim about him is that he's such a good puck mover. Can anyone tell me how/why they believe Carle is seen by some as this great puck mover? I mean, he didn't really skate the puck out of the D zone much at all, like you see from the better puck moving d men in the league. His primary M.O. when starting from his own end was to go behind the net, move over a little and if the (risky) stretch or cross ice pass wasn't there, get it to his D partner. I mean how many times did he just simply pass to Pronger who would then make an excellent outlet or skate it out and up to the red line and fire it on net? It was a lot. In my recollection, it was rare that Carle was really keying the breakout. In the O zone it's not like he was some great puck distributor or PP QB. Can anyone that feels Carle is/was a great puck mover describe to me in specific terms exactly what he did out there that made him such a good puck mover? I just don't see it.
Carle didn't win a lot of puck battles along the defensive boards so it's not like if he was here all of the sudden the team would be clearing pucks with ease. It's not like the team didn't have times hemmed in their own end when Carle was here (really, it happens to all teams at least once or twice a game).
And I'll say this, looking at the past couple of games and some of the others where the team played well, guys like Grossman and Gervais and Schenn repeatedly make puck moving plays out of the zone on par or better than Carle, while being more stalwart and physical on D. All of those guys are underrated in terms of moving the puck from what I've seen.
