Perhaps. But there's a photo of Ted Williams at absolutely his most exuberant. He just hit a game-winning dinger in the All-Star game and is running and jumping for joy as he rounds the bases. He was an incredible hitter who batted .388 (in 547 plate appearances) when he was 39 freaking years old. He lived to hit and was very analytical about it. But I'm pretty sure he never came close to that sheer joy after hitting a single, double, or the rare triple.
I'm sort of anti-homer, but the simple fact is that dingers have a lot of potential to be game-changers, as Dalbec showed last night.
And the other fact is that, your 5.000 notwithstanding, 1.200 is a fantastically high OPS, and it's less that 1/4th of 5.000. So, yeah, a dinger provides a great high, but accumulating at bats brings most players back to earth. Williams lifetime OPS was 1.116 and Ruth's was 1.164--the two highest in MLB history.
