Seems logicalIt does seem to be odd timing unless he’s leaving. He signed a 6 year contract with PSU that runs through 2025 so there’s no urgent need to be changing up his agent mid season. Do it in the off season when it’ll barely be a footnote on the sports page.
The main reason to do it now is that you expect to be negotiating a new contract shortly. The only other possibility I can think of is some significant/ urgent issue causing an irreparable fallout with his current agent.
