With all due respect, it does make a difference that Matt Kemp has shown up to camp in better shape. It’s better not to be fat, especially if you’re a professional athlete. And when advanced metrics, inexact though they may be, rate your defense with frowning emojis, it’s encouraging to see a player take steps to improve.
Fans like to see players motivated. Especially when a player is making $18 million a year. Losing weight is a sign that Kemp means business. Twenty pounds, or whatever he lost, may not amount to much, but it’s not nothing.
