The irony of insinuating that Isiah Thomas is overrated when speaking about him in comparison to Cliff Paul
But to answer the question, Isiah is better at playoff success, fair or not, that counts for a lot when we rate players greatness. For example, Karl Malone and Charles Barkley would be looked at much more favorably if the would have won rings. Imagine if John Stockton would have won a few rings, they would have that boy as a top 5 player

It is what it is man. Cliff needs to win something or history will not be kind to his legacy.
