Maybe the guy looks at like this: His OBP is directly related to him hitting so many home runs.If he didn't hit home runs his on base percentage would be a lot lower from not getting walked as much out of fear, making him somoene with a .263 AVg and maybe like a .330 OBP.
Also, lol at everyone using AVG here when all the time people say its a useless stat with no meaning and it's outdated, etc.
