Does Bowey have more value than Reinhart alone? That's my point. Not that Reinhart and Yak are world beaters but I still think that both would have more value than Bowey based on what I saw of him a little over a year ago.
For Capitals, easily. They don't need Griffin Reinhart at all really, as long as Brooks Orpik is on the line-up. Can't afford to have 2 guys on the left-side that provide absolutely zero offense. Especially when they have Nate Schmidt ready there too, who provides very little on his own. Both Orpik and Schmidt would play over Reinhart, which would lead to him being #7D for Capitals. It's a different question if Brooks Orpik would be going the other way, too.
As good as it might be for Yakupov's career, Capitals don't need him, at all. Their LW depth is among the best in the league, and only one Yakupov could have chance to compete with is Winnik, but Winnik fits better on that 4LW role as he plays major PK minutes too. On the right side, Capitals are set all aswell. Williams and Oshie over Yak are no-brainers. Wilson takes one of bottom-6 RW roles, and Yakupov doesn't really fit over him either, because Wilson is key PK player on one of the best units in the NHL. They already added Brett Connolly, who is a similar player as Yakupov, but he came without any assets going the other way, and his salary is far more realistic for what role he is going to get here.
Madison Bowey just had a really good rookie season in the AHL, and has been developing really well after being drafted. I don't know if he's more valuable than Griffin Reinhart in vacuum (IMO, he is), but for Capitals he is much more valuable than Reinhart would be. Only way i would ever consider this is if Brooks Orpik was going the other way too. Otherwise, Orpik is taking the role already what Reinhart would have in Washington.
