In simplest terms
1.People make comments about acquiring Trouba or Subban. These moves require further moves to make fit. Backtrack to how we have been inactive for over a year bringing talent in. Usual comments are ‘two to tango’ or ‘no need to overpay’.
Now back to acquiring a RHD. Making moves that require further moves yet weve been unable to make ANY moves to bring in talent over a year.
Have these barriers that have stopped us thus far vanished? Thats Part 1.
Then we have people who GENUINELY believe RHD is more of a need than LHD (which is mind blowing, really). Yet another move is required to fill the only truly vacant spot on defense.
That goes back to step 1 and then jumps to step 2 - getting all these deals done in one off-season and not overpaying drastically for it
Whereas if we simply acquire a LHD...........
Part 1. Maybe we havn't made any moves recently because it wasn't the right time. People bring up Grabner as a mistake, one Shero might of had to make or not, depending on how you look at it, it's a convo that's been had too many times already, but still, it ended up not being the right move and at the wrong time. Maybe Shero has hunkered down a bit more since then waiting for the right time to get back out there. I believe this team has been in a period since then where it is more of a let things settle, let prospects come up, let's acquire assets and get back at it. I'm sure if another Taylor Hall fell in his lap he would have taken it, but there was no reason to go after that stuff.
So with all that, if he is, as a lot people believe, ready to go for it, there is absolutely no issue in making trades that then need further trades to make work. Of course at some point he might over pay a bit and or lose out on someone because they just didn't have a place on the team and other GMs knew it. But at the end of the day if it makes the team better overall and more set up to start contending, it would be worth it.
Part 2. You will need to point me to the people who "GENUINELY believe RHD is more of a need than LHD," I don't seem them. What I do see is posters talking about a lot of upgrades on defense which mostly happen to be RHD. There just isn't a lot of top teir LHD for the taking at the moment, so obviously they get talked about less. Our defense is overall, nothing to write home about. Upgrading either side would help A LOT. A couple reasons why, first, you can use the RHDs that get pushed out, package them with other assets and try to then upgrade the left. Another option is moving guys we aren't going to get rid of, over to the left. And last, if we get a RHD who is better than all of our other RHD and one of our current RHD just magically poofs into thin air never to be seen again with out anything in return.... and C+,LHD and A ,RHD pair is STILL better than a C+,LHD and B-,RHD pair.
"Whereas if we simply acquire a LHD" I'm sure if one comes along, who moves the dial enough to give up assets and is available to the NJD, it will happen. But if it doesn't, it isn't the end of the world.
