Dude you're not the only one here who witnessed 1987. I'm sure you didn't watch many other teams games that year either. Personally I love to know how a player performs compared to their peers. Statistics allow us to do that. No matter how much experience you have watching baseball you can't possibly give us a better scope on performance than stats.
In 1987 Andre Dawson was 24% better than the league average hitter. He didn't like to walk and 40 players across baseball had more impact offensively, 14 in the NL. He didn't provide much value in the field or on the paths. He really didn't deserve the MVP. Would you give Matt Olson the MVP this year? Very similar seasons.
Pete is the 2nd best hitter in baseball, the best fielder at the hardest position, and is gonna steal 40 bags while blowing the competition away in runs scored.
Yes he's been 3x better than Dawson.
