Don't see any reason to break up King-Stoll-Brown. Their straight forward style has helped Brown a ton. They're a ridiculously good third line with Brown playing well.
Kopitar and Williams have always been great together and it's no secret that finally reuniting them has made both players look better. If Gaborik can effectively play LW, he's either with Kopitar/Williams or Richards/Carter, with Toffoli taking the other slot.
No reason to drastically shake things up when they've been working. The only odd man out is Pearson, which is how it should be.
