Exactly.
Sexton isn't going to sacrifice a single dollar. Of course he's not going to come out and say it – he doesn't have to. It's gonna be the old "Of course I'd like to stay here, but in the end, it's a business... so we'll see." That's NBA code for "Money talks, MF".
It's impossible to overstate the importance of the 2nd contract for a guy like Sexton. He's not a sweet-shooting, crafty big man who can make money in the NBA until he's 37. Jitterbug shooting guards relying on their quickness tend to have a pretty short shelf life in the League.
