I dunno, some people just don't get that certain stats are stupid like ERA, dont understand park factors, use bad sample-size based arguments because they don't know what a real sample size is for the numbers they are quoting, and you end up with this train wreck where someone is so confident that what they are saying is true, when in reality he's further out in left field than that monstrosity in the Marlins home park.
It's entertaining really.
