Scratching Stanton in favour of Weber and Sbisa is pretty ****ing stupid if he's ready to hit the ice.
For whatever reason, Sbisa is playing better hockey with Weber than Stanton and Weber is also playing great. Sometime you don't mess with a winning line-up even if it means a better player is sitting out.
Also Weber can play on the 2nd PP unit, Stanton can't (nor is he a RHS). I guess you could make the argument of Stanton > Sbisa but at the same time Sbisa has been playing very good hockey and even contributing a bit offensively.
Basically you really can't go wrong playing Stanton/Sbisa/Weber right now, which is a good thing. I would just follow the saying of don't fix what isn't broken. The only change i might make is get rid of Sestito in favor of Horvat than Burrows since the winning streak started with Burrows in the line-up.
