Well if you consider that every soft pass right to the other team, every ill-conceived pinch, and every time a goal went in against him while he was out of position facing the back boards was ACTUALLY the fault of Joe Corvo, I think these numbers actually make a lot more sense. Context is important.
Besides, no one looks at +\- anyway. The real stat we should be considering is his CCRVF%. For those unaware, this measures time on ice against skate size and factors in how many marshmallows the player can fit in his mouth at one time. Lohrei is actually in the top half of the league.
My honest true opinion?
I like Lohrei. He's young. He skates great. He does thing with the puck that nobody else on the team can do. I think he's the best PPQB on the roster. I think he was a hell of find by our amateur scouting staff and I have high hopes for him.
I'm concerned about Lohrei. The progression that I hoped to see from the beginning of the season to the end never happened. He's soft in coverage, soft in his puck distribution and far too often lost in coverage. If you're only as strong as your weakest link, the kid has to get a hell of a lot stronger in these aspects of the game or he's gonna end up a lanky MA Bergeron... And the blueline will suffer for it.
He limits his limitations and we have one hell of a player. But how we get there? I haven't the foggiest.
