What's it to you as long as he hits it 3 out of 4 times and manages his bankroll effectively?
To me he's demonstrated at least a passable level of baseball matchup knowledge and team playoff positioning/motivations to earn a level of respect.
If he were only hitting 60% of his huge chalk plays he'd deserve more scorn and he wouldn't be so cocky. But from what he's posted he's batting well over the Mendoza line for a profitable season.
