Hartman says no.

Name me a player who waived their NMC after just being extended for 3 years? Yeah Hartman isn't going anywhere. Especially not for that offer.

I don’t think Guerin is trading Hartman.

You can't retain only on one contract.

This...

Never happened. It would be terrible business.

I think you actually can. I just tried it in a fresh armchair GM and it only retained on the active contract, not the extension. This was a topic of conversation last season when their were JT Miller trade talks. I don't feel like looking up articles right now, but I definitely remember writers mentioning this when talking about potential landing spots.

From what I remember is you can only retain a % which oddly isn't a feature on capfriendly (they make it a dollar amount). Anyway the % carries over.

I just found an Athletic article from last deadline and it looks like I was wrong, retention must be done through the entirety of the term they're under contract, not just the active contract. I knew that retention needed to be an equal % across all years of the contract, but wasn't sure if that included if there was an extension. I must have been remembering some speculation from before they got clarification from the league since signing a long term extension then immediately trading the player with money retained hasn't happened in the cap era as far as I know.
