I think people are getting out of control here. Parsons has a cheap option, yes. But his cap hold is like $1.7 mil. Still cheap. However, he's also a restricted free agent. Next year, if they exercised his option, he'd be unrestricted, and could go elsewhere without the rockets having a chance to match. This move will help them keep Parsons long term, without costing much cap room. Sure, it also opens up a sign-and-trade if Parsons wants to be part of that, but mostly it means Parsons can't leave without the Rockets getting right of first refusal. It also probably creates goodwill with Paraons, who will get a big raise this offseason, instead of next offseason. It has very little to do with their machinations towards Melo, Love, or any other player the Celtics might be interested in.
