While both Butler and Harris will be eligible for the same 5-year, $190 million max from the Sixers (and both will command at least close to that, given the number of teams with max slots available), Harris’ cap hold will only be $22.2 million. That means, if things go south with Butler and his future with the team, the Sixers — by renouncing the rights to Butler, Scott, Boban, T.J. McConnell, Redick, et al. — could still fit a 25 percent max contract in free agency, while still keeping the core of Embiid, Simmons and Harris in place. They’re a Zhaire Smith contract away from a 30 percent max, and they could even get beyond the threshold for a 35-percent max if they move off of Fultz’s $9.7 million contract for next season.
This is where making the trade, rather than pursuing Harris in free agency in July, presents the Sixers with a couple of advantages. If Butler fits in with the core and wants to return to the Sixers as a free agent, the Sixers would’ve previously had to renounce Redick’s rights in order to have the cap room necessary to sign Harris as a free agent. Now, with rights to Redick, Butler and Harris, the Sixers can go over the cap to bring back all three. If they decide to move on from Butler for whatever reason, they have Harris’ low $22.2 million cap hold on the books, and will have cap space to replace Butler prior to giving Harris his new larger, long-term deal. It increases the upside of either scenario.
