Booker might be a “Franchise player” for a middling playoff pretender type team, but I think jury is still out if he can be a “Franchise Player” for a title contender year in, year out. The straw that stirs this team’s drink is CP3, IMO. He can consistently control a game/team as the unquestioned leader all on his own, totally control at least half of the game and be able to do so either by scoring or initiating an entire offense successfully. Book has yet to prove that.
But he’s definitely taken steps forward towards that goal this year. Even from first half of the season to second half, I’ve noticed his passing ability has risen. The Lobs to Ayton have become much much more consistent and he’s added those laser bounce passes great passers make.
What's the definition of a franchise player? Because there are only a couple players in the entire league that make you an instant contender (i.e. LeBron). Outside of that almost every franchise player in the league needs a 2nd high caliber player to play alongside and get you there. Clearly, CP3 is perfect example of needing that other player to take the pressure off of you. Teams have been keying on Booker since he got here. He has basically been doing it himself.
I would argue that if he had that caliber player playing next to him the entire time, few would argue he is a franchise player.
It's an interesting argument because people all seem to have a different idea of what a franchise player is and even then often let the entire max player issues blur the discussion.
