This is a good move for Memphis. They needed a player like Mayo to boost their attendance.
players don't boost attendance, winning does.
Only in very rare cases, like elite super-duper stars such as LeBron, will a player fill seats everywhere he goes.
Have you ever been to a Memphis home game? I have been to several and I guarantee you this guy will help boost their attendance (which has been worst in the NBA), next year.

sorry I don't buy "guarantees" from fans when we've seen this thing a bunch. They'll be some minor boosts early in the season due to the "promise" or "hope" or whatever. But if they stink (and they will), the fans will stop showing up. Attendance analysis has been done a million times over, for all sports, and it all points to: winning fills seats.
The Celtics are lucky in that even when they stink, we do a solid job filling seats, but we still saw a huge, huge boost after the trade. When we won 33 games with Paul Pierce and Al Jefferson (a true star AND an up-and-comer), Celtics ranked pretty low in attendance (18th total, 20th by percentage of max). Is OJ going to fill seats better than Paul? Sure at first, due to the hype, but he has to become LeBron/Kobe/AI for it to keep filling them if the team loses. They need wins, and unless Wallace makes a few great moves (doubtful), they aren't going to get any.
I'm willing to bet that as the team stands now, they're still a bottom 5 team in the league in terms of attendance.
