If "YOU SUCK!!" counts as an issue. But, for the most part, I don't really pay attention to the officials. I didn't pay to see them officiate.
Evidently you did not.
Probably not. But, if there is going to be one, he'll need to start his career when he's 20-21 and hang on for those last few years to make it. It's much easier to average 15 wins over 20 than 20 wins over 15. What makes it more difficult is that he'll need to pitch for a contender that will give him a few wins when he gives up 5 runs in 5 1/3. And most contenders aren't using 20 year olds because, well, they're contenders.
