Watching the highlights, you can see Kosko he uses near the same approach as Rinne. Big goalie that relies on his size, reactions, and athleticism. Biggest difference is Rinne is quicker to get back to his feet while Kosko can start swimming. Though how much do the teams and defences in front of them impact that?**
I can see why the team likes him moving forward, but with his style his endurance is likely to always be questionable. Though if Smith's on the same page as him, he's a guy that may be able to help Kosko with his game, considering he's made a career of also playing that very style.
On that note, this is one thing I'd be weary of with Talbot if I was Calgary. I think it's clear he's walking into that situation looking to win the #1 job, not so much to mentor/help Rittich. It's a bit of a red flag in my book that Philly chose Elliot over him to backup/work with Hart.
Now Smith very well may have the same issue, but at 37 and already having this situation last year, I can see him being a bit more mello. Plus with his bonus structure, he's incentivised to help the team get to the playoffs, vs. just steal the starting job from Kosko.
**Also I'm not questioning that Rinne is a better goalie, but we've seen when Nashville's defence starts to bend and get figured out, he struggles to compensate and looks like a fish out of water too. It's just what happens when this style of goaltending gets exposed.
