Dubinsky - As I just posted I think Dubinsky should be around 55-60 pts this year. 60 isn't out of reach. He'll be used in a secondary role once Prospal is back due to Tort's favourtism of the Gaborik-Prospal duo. But, towards the end of last season Gabby and Prospal were split up...so that could leave a hole for Dubi. Dubi is just a hard working-never take a shift off player. I must say that Dubinsky is playing a lot better offensively compared to his past and I would not be surprised if he reached 30 goals (thats a lot of optimism!).
Callahan - This guy is a Torts favourite simply because every shift he gets at least one hit, one shot on goal or one blocked shot. Simply put: he's noticeable on every shift. The problem with Callahan is that he'll always be behind Gaborik or the next superstar that comes to NY on the depth chart. He's more of a PK guy with not much of a scoring touch. I can't count how many opportunities he's missed this season. For Cally, I'd expect around a 50 pt season with 20 goals. Another thing is that the Rangers are almost cash strapped after spending on superstars so the 2nd line is always either prospects or try-out over-the-hill vets (no offense Fedotenko hes been playing well).
Hope that answers your question! Thanks for checking out the Rangers thread!
