Komisarek is quite clearly a defensive defenceman. I thought it would be hard to come up with similar players but I'm pleased with these lists of past and present defensive defencemen. Rather than points, I used games played and ATOI.
Regehr and Hannan are way ahead of Komi in terms of development. They're among the cream of the crop of shutdown defencemen. Hannan's cap hit is $4.5M. Next season Regehr starts a 5 year extension worth $4M per.
Mitchell and Schultz are a tier down, and still appear to have progressed more rapidly than Komisarek. How much of that can be credited to playing on top defensive teams? Mitchell signed for 4 years at $3.5M two years ago. Schultz just signed for 5 years, also at $3.5M.
Colin White cracked a deep New Jersey blueline at a younger age than Komisarek. Two seasons ago he signed for $3M over 6 years.
I think Volchenkov is the best comparison among Komi's contemporaries - a top pair, right-side hitter/shot blocker. Their development curves are pretty close too. He signed his final RFA contract last season, for $2.5M over 3 years.
Sarich is a RHS whose development might be a little behind Komi's. He got lots of minutes on the AHL-calibre defense in Tampa. Last summer he signed for $3.6M over 5 years as an UFA.
Commodore and Vishnevski are a rung or two below Komisarek. Vishnevski got $1.8M per as an UFA and we'll see how Commodore fares this summer.
These are some players whose early seasons were similar to Komisarek's, just to get a feel for how his career might play out. Jason Smith and Brendan Witt progressed at a rate similar to Komi.
Being paired with the team's best defenceman gives his numbers a boost, so the potential is there for an overpayment on the UFA market next summer.
