Your evidence is faulty.
First of all, Pargo took the last shot in a game with a 9 point difference. Unless that lay-up was going to be worth 9 points, it doesn't matter who takes that last shot in a game that was decided at that point.
Second of all, Paul was being guarded by Bruce Bowen most of that fourth quarter. Deron Williams was being guarded by Derek Fisher for most of that fourth quarter. Fisher is still a decent defender, but this is not the first time Bowen has played great denial defense on a player.
Third, Pargo was shooting ing lights out. A selfish egotistical player would have taken all of Pargo's shots in that fourth quarter. He scored 16 points in that quarter. It would be something different if Pargo missed all of his shots. He didn't. A good point guard keeps milking the hot hand.
Fourth, Okur and Kirilenko made the big three pointers in that Jazz-Lakers game that even allowed the Jazz to have a chance to tie that game back up, not Deron. 1:02 left in the game, down 9, Okur makes a three pointer, Kirilenko makes two three pointers, Okur takes and misses another three pointer, with 4 seconds left mind you. That was the real last shot if you paid attention to the play-by-play. Deron Williams' last shot was off of an offensive rebound scattered play.
