He was basically saying that in response to questions asking him about coming off the bench though. Like "hey you come off the bench, must suck huh", so the response of him saying he would start on most teams where he isn't backing up AD or LeBron was fair. I don't think he's wrong either.
He has the awareness to basically understand that he would start in most situations but is also willing to come off the bench and not chase money because he's in a great situation. I actually think both comments go hand in hand with one another.
He definitely knows he can get traded at any second, but it's unlikely he's traded this year after signing an extension. Since he signed an extension that doesn't start until next year he has a poison pill contract. His outgoing trade value would be in the 10-11 mil range rather than the 3.5 mil he's actually being paid. Normally that wouldn't matter but the Lakers can't bring in more salary because they used their MLE to sign Trez. They are basically hardcapped to stay under the tax for this season because of that.
Any trade for Kuz would likely have to be some package of Kuz+Harrell/KCP where the money goes up enough that the other team is only trading out the 80% required and the Lakers bring back equal or less money.
It's highly unlikely such trade even exists. For example 80% of Kuz+KCP salary wise is around 17ish but combined this season they are around 15.5ish and unless another move was made it's not possible because the Lakers basically can't add salary. Most realistic would be KCP+Harrell+Kuzma as 80% trade value is around that 24-25 mil mark which is what the 3 of them are currently making this year. Trick would be finding a player or combo of players that equals their value for 24mil. But it is possible.
Long story short, it's highly unlikely Kuz will be traded this season or that a realistic trade even exists now that he's signed a new deal and Harrell signed using the MLE. Most realistic trade would be where a team uses an exception like Golden State used to get Oubre, but the Lakers likely aren't losing Kuzma for only a pick in return when they will be over the cap next off-season and unable to pay anybody to replace him. He's likely safe for at least 1 more year.
