‘Some players do well and some players struggle under Ruff’s system. The players who succeed, like Jason Pominville, have two-way talent. It appears the system isn’t going to change, so the roster has to. Running three purely offensive lines and asking several one-way players like Leino to work in both ends is asking for either failure or a long adjustment period (which may be the case with Leino.) The challenge is whether the Sabres can find those players and put together a 2012-13 roster that fits the “system.”’
