I agree that a lot of the match ups are pretty "convenient," but you're grasping at straws with several of those. Rukia was by no means "weak," nor was she even the weakest out of her group. Grimmjow was never the main antagonist at any point; he was just another obstacle that Ichigo had to remove. A couple of the other ones are also pretty vague compared to obvious ones like Mayuri v. Szayelaporro or Nnoitra v. Kenpachi.
