I still think it matters from a Team perspective. It's pretty rare that a Team makes the playoffs, and rarer still that they do anything when they get there, if they are significantly below league average for Team HR power. You can look it up. I have. Last year in the AL of the 5 Teams to make the playoffs: The Yankees led the league with 241, the Astros were second with 238, Cleveland was right above average with 212, Minnesota was right below average with 206 and Boston was dead last in the AL with 168 (but still ahead of the Braves 165). League average was 211.
In the NL it broke down like this: The Cubs were 3rd in the league and had 223, Dodgers 221, Diamondbacks 220, GNats 215, Rockies 192. League average was 196.
So yes, the HR numbers were inflated, but once again the best teams were at least league average or better in Team HR.
The real outlier from last year was Boston. They were the second best pitching in the league behind Cleveland but their offense was nothing special.
In a typical year, historically over the last 25 years, team average for HR is about ~150. If you look at the current and projected Braves team: Freeman (30-40), Catching (15-25), Albies (10-15), Swanson (10), 3B (10-15), Markakis (5-10), Inciarte (10), LF (20-25), Bench (10-15) gives you a team projection of about 160 team HR for 2018 assuming top end HR production for everybody. So, unless you believe that the pitching staff is going to be one of the best in baseball (and I don't), then statistically and historically, this isn't going to be a team that competes for anything. As everyone knows RF and 3B are serious problems for the Braves.
