Since when is shooting a majority of your games over 45% pathetic? Maybe by Kobe standards its pathetic.
You're also forgetting he averaged more PPG than Lebron James and was just barely beaten for the scoring title by Kevin Durant. Both those players are bigger, stronger and get to the basketball more than Kobe. Kobe's age has begun to catch up with him and he doesn't get to the basketball as much as he used to. Again, if you played the sport you would know that the closer your shot, typically the higher your FG%. Same reason why post players typically have the best FG% in the league. Hell, according to your logic, Pau Gasol is a better scorer than Kevin Durant, I mean he shot a better FG% than him. Dwight Howard is also apparently a more offensive threat than the top 3 scorers in the league (KD, Kobe, and LBJ).
For the kind of shots Kobe takes, having a majority of your games with a greater than 45% FG percentage is impressive. He's not dunking the ball every other play, 4 out of 5 of his shots are jump shots.
