If he tops 20 PPG, he will beat Roy in a stat by stat run down based on the ones you listed.
Points would be close. And ya, acting like someone who is a legit scorer with range and good %'s jumping from 15 to 20 is the same as comparing him jumping up to 12 boards (best in the NBA almost) and " ting out Magic Johnson". Good call
Based on his production NO ONE SAID HE WAS THE BEST PLAYER. WTF is your point? That is not the argument. He is a top 4 player from the draft now and could easily jump to #2 if he keeps improving. If he goes over 20 PPG (which is not a stretch) he will be the 2nd best player (or arguable with Rondo).
Not worth it in your eyes, but when you look at his skill set and size, the contract is not that far off.
