Yeah its so dumb, he says "I trust all my teammates" but then goes on to say "any ball I can get to, i'm going for it" and "I have one of the best arms in baseball".
If he actually trusted his teammates, he would have let Randy take the throw. This was not a situation where they both had to run about the same distance. Randy was camped under the ball preparing his momentum while KK was still trying to get to the ball.
