I see a 20 yr old who still has yet to fully grow into his body. By the time he is 23 he is gonna be 220lbs. I've seen his homer rate increase as he has moved up levels. The biggest indicator to me that he will develop more is the rate at which he hits doubles. Last yr 36 and this yr 23.What in the world would I be mad about? Just giving my opinion. If you objectively look at that swing, I don't know how you can see plus power, let alone plus plus power. I never said he had a whole in his swing, or that he wouldn't be a good hitter. Can he hit 10-15 homeruns? Sure, I just don't see 25-30 homeruns a season. Do you?
By the way, your stats actually are in my favor 7 homeruns in 300 at bats is far from impressive, the BA, hell yes it is, but not the power.
