I still think the bigger problem is a large amount of roster redundancy with SAH d-men. Our only real puckmoves are Drew, Muzzin 50% of the time when his brain is functioning, and Martinez who unfortunately has to play on his backhand/wrong side because of these redundancies. Then you have a whole slew of guys like Folin, Gravel, Forbort, MacDermid, etc. who are depth SAH types who are exposed in higher roles. So, the problem is our puckmovers are our #1-3s, and our SAHs are our #4-50s. Need a better distribution of that and LH/RH in the lineup. If LaDue can keep up, that's a problem he begins to solve. But it's bad having a Doughty-Muzzin pairing when behind them is a bunch of guys who can't get out of their own zone effectively, and it's bad having a Muzzin-Martinez pairing because then Doughty gets an anchor so opponents can just double him (not to say anything of the muzzin-martinez dumpster fire).
In other words, bad roster composition rather than bad talent, and I think a guy like Forbort gets made to look worse because of it.
Not that it really supports that he's a top 4 d-man but to be fair to Forbort he's got abysmal usage. He's getting the Vlasic-style set up to fail deployment. Granted, some of that is because he's terrible on offense, but he is a defensive d-man that could hold down the #4 spot if we had a Voynov-type #3 imo. I wouldn't begrudge anyone for thinking otherwise and ideally, like Martinez, he's on a third pairing.
