you're being too simplistic when it comes to the game of basketball with this assessment.
Manu's points are different from Parker's.
TP had a low amount of points, but the entire Heat defense was focused on him. Ginobili wasn't the focus of the Heat defense and didn't do well.
when you take that into account, TP didn't really have "a bad game" while Manu didn't have a "good game". the ball movement from double teams that Parker would face help confirm that while Ginobili didn't have that same scheme.
now Bonner. yeah he sucked, but he only played 12 minutes anyway in a game that was meaningless for the majority of those minutes. in other words, Bonner's play really didn't matter anyway. that's like arguing why Patty Mills sucked in garbage time.
Bonner is one of the last guys in the rotation in this series unlike when he was a huge factor in the LA Lakers series (mainly because of LeBron at the 4), so your Bonner hating fetish has no basis this series. if you want to get on someone, get on Ginobili who hasn't shown up at all these playoffs. he's part of the Big 3, Bonner is just a role player.
