I think this was the line of thinking as the play went on...
First Pierce wants to make sure he doesnt dunk it. Then Pierce holds him so they both dont fall.
James thinks the hold is excessive and throws the elbow.
Pierce takes offense to the elbow and holds on to him longer.
James mama comes out cursing and James tells her to stop.
James realizes that Pierce wasnt initially trying to start stuff and goes up to him. Pierce realizes how James could've taken it the wrong way. Both acknowledge that there was excessive physical contact throughout the play (with Pierce thinking, if u cant elbow me like that, and James thinking, u cant hold me like that). However, both know its not a big deal.
They kiss and make up at FT, play over.
