Even if you think Paul is better than Rondo there is no arguing that Rondo is one of the top 3-5 PG in the NBA.. why upgrade that position? I'd be more concerned with who is gonna replace KG and ray ray and eventually PP.
Not to mention rondo is SO much cheaper than paul, already a fan fav, already knows the system and has a relationship with DA.
He's proven that the team can win with him as the PG. He played great in the LA series for the most part(free throws not included) but Ray Allen couldnt hit a shot, KG looked tired, Pierce played well but not well enough, perkins was constantly on the verge of getting a tech and getting booted. Wallace was hurt the whole series... There's so many reasons OTHER than rondo that could explain why we lost....
If it aint broke dont fix it. We need a younger backup shooter for ray and paul, we dont need another top 5 point guard
