I don't disagree with that in general. But its important to point out that Josi was almost a year younger in his draft year than Reinbacher. So if you adjust the comparison from draft to birth year their production is very much comparable in a vacuum. Also when Josi was only slightly older than Reinbacher is now he was already the best player in Berns championship run in the NLA that year. I remember that pretty well. Thats no knack on Reinbacher but I don't think he at 19 is as good a prospect as Josi was at that age. An that is factoring in team/league context.
That's true but I think they're difficult to compare. Firstly the NL was nowhere near as good back then as it is now. It's arguably the best league outside of the NHL today or pretty close from that at the very least whereas back then it wasn't as nearly as good as the KHL and also definitely significantly worse than the AHL or the Northern European leagues. NL was stronger during the lockouts but they were 04/05 and 12/13 so not when Josi played for Bern.
Also, Reinbacher was the best player on Kloten's team and with his playing style he depends on capable teammates more than Josi does because he's less of a puck hog and possession monster but more of a fast paced hockey and transition guy. Josi is also much better on the PP which of course did increase his point total. Reinbacher didn't get much PP-time and Kloten's PP was trash this season anyway. Also, Reinbacher does play heavy minutes but is best used and most efficient at even strength which means that he's scoring less but doesn't make him a worse player in my view. Also, on that loaded Bern team Josi was on, Reinbacher would have scored a ton as well.
So you definitely mentioned some very good points but I think they're really difficult to compare because their situations were entirely different and so is their playing style. We'll find out what Reinbacher is all about over the next two seasons I think. I'm not sure Reinbacher is gonna be as good as Josi who's of course an absolute superstar and franchise defenseman but I wouldn't bet against it either. It's certainly possible and I think the upside is there. His play this season is kinda difficult to assess so we'll have to wait and see.
