Between Dahlin and Power, we already have his skill set in the top-4. He's not the veteran presence (e.g. Roy, Pesce, Hanifin, Andersson) we were hoping for. A "nasty streak" and a willingness to fight with 3 concussions already in his career is scary, frankly, for him and the Sabres. The youngest team in the league just got younger. Whatever magic he can work on the PP will be limited; maybe he can displace Power, but he'll inevitably be a PP2 option at best.
I hate this, but Bo is a Sabre now. I'll be cheering for him to blossom in blue and gold. Let's give the kid a chance.
