That's not the point with Fisher obviously. The point would be that he just got done starting for like his 37th championship team and might be the saaviest veteranist winningest "veteran leader" you could import. That in an emergency you could call upon a guy with 5 rings to just step in, bring the ball up, and knock down clutch threes is just icing.
Fisher is the guy you get when you are a team that doesn't really need anything. And really, we don't. Our little nitpicky holes are a 3rd string PG, which Fisher would cover, and maybe some extra distance shooting, which he would again cover. Everything is accounted for. So picking up the vet champion to dispense wisdom to the kiddies on the way out the door is a viable play.
