In what way? Why is Borgman rarely playing then? Why is he not out in crunch time, or playing 18-20 minutes a night, or getting any PK, like Hunwick consistently got for the Leafs? Babcock may have a predisposition to vets, but he'd play Borgman more than 13-14 minutes a night if he was capable of doing it.
And it does not surprise me either. Borgman-Carrick get baby minutes when they are together. If they couldn't handle that, then there is no reason either should be on an NHL roster right now.
I found the tweet, but there was something that compared him to league average. He says that it comes down to system more than skill, which is somewhat true, but then why not just have your worst players playing that all of the time? Why isn't Borgman a top PKer while Hainsey and Rielly still have to do a lot of PK on top of their ES and stuff? There is some sort of skill involved in PK, even if it is just picking up the system and knowing where to be in the defensive zone. Not every can do that at the same level as people like Polak can, and maybe that's why Babcock trusts him.
The league may be moving towards more puck moving defensemen, but I do not think we will ever see a defense fully composed of only puck movers. Guys like Polak are still necessary. Now I think if there were younger Polak's out there they would have to make sure their puck skills and skating skills were more up to par for the NHL than they were when Polak first came in. So maybe you want a sort of hybrid between Polak and Hainsey. Tough like Polak, a little bit better with the puck and skating like Hainsey. Sounds a lot like Borgman, but one common them is strong defensive awareness. Borgman is not there yet. He's young and he needs time. That's why I am content with Polak in the lineup for now (and sending Borgman to the AHL but that's irrelevant).
Like I said every year since dealing Polak to San Jose, I hope we do not have to bring him back next year, because that likely means our prospects are finally good and ready enough to properly replace him. I want them to get to a point where they can play PK and at least 16 minutes a night like Polak is getting. But they are not there yet, and until they are there, I can not see how you can fault Babcock for giving them the time they clearly need. Defensive development is something that needs to be done right from the beginning, or not at all. There is more room for forwards to be able to learn as they go if you need to (although clearly Babcock does not even want to do that until a spot truly opens up), but it's hard for defensemen. All I want out of Babcock is to make sure that when the time and opportunity comes, they do get that shot to take the next step.
