You’re not wrong, but Kyrie works really well in small burst of ISO and does not need to really drive most of the offense for a team and imho having CP3 as a mostly spot up guy is kind of a waste… in the end it all comes down to the contract he would be willing to sign, if he is dirt cheap and I was the Lakers I would still take him in a heartbeat for all the the reasons you said

Also there is a very real possibility we lose Grant in free agency

feels like a bad fit to me, LeBron and CP3 both need the ball in their hands to be at their best
