This is one step below Love and Rondo shaking hands at Fenway Park. There was certainly aome ambiguity about a possible 'beef' with IT and Cousins so this makes it clear that there is not.
Also, if Cousins is worried about IT being a ball-hog, it actually works out well for them on the Cs as IT comes off the bench for us. Sure they would play minutes together, but not all minutes like when they were on the Kings.
