They (Berube and Treliving) never really sorted out the bottom-6. It was pretty much just a collection of spare parts thrown together in various combinations, hoping something would take. They need to figure out what those 2 lines are supposed to be, and adjust the personnel accordingly. Do they want two shut down lines, a sheltered scoring line and a crash line, some other combination...identify what that is and make the changes needed to get there.
Personally, I'd love to see some type of "crash" line that is willing and able to consistently punish opposing defenders. You would think Lorentz maybe could be that guy, but he doesn't really seem to be into that kind of game. Most of his "hits" on Florida defenders appeared to be half-hearted at best. Some of that was the interference that kept Leaf forwards from getting in on time though. Maybe that isn't important to Berube and Treliving and fine, if that's the case - but identify what you want and make it happen.
Someone in that group needs to be capable of putting the odd puck in the net, regardless of what they decide on.
Bennett...I would hate to have him on the team, but that would probably be preferable to having him on Florida. I suspect he'd be suspended for the first borderline hit as a Leaf.
