Impactful in the baseball zeitgeist, not in terms of production. He's always produced and will produce. He's an elite HOF hitter. But he's not even 30 and he's already fading away as a marketing arm of the league. Ask a collection of younger fans who their favorite players are and the vast majority won't throw Bryce's name into the ring. Him signing in Philly and the team tanking the last few years has murdered his brand because he's not playing in the postseason and he's so outwardly depressed compared to his personality on the Nats. The HR Derby in 2018 was like the peak of his brand so far. Guy will still go into the HOF as an elite hitter but man just feels like he's in the background doing it.
I don't consider him an elite hitter, not that you have to be one to be in the HOF. Very good and will move up in some counting stats, but Boswell always compared him to Reggie Jackson. That's HoF profile, but not elite.
Here's a guy who is a similar hitter that no one thinks was a HoF:
20 seasons, 440 HR, .277/ .399 / .516, wRC+ 140.
Bryce:
11 seasons, 282 HR, .282 / .392 / .529, wRC+ 143.
Given he's in his back-half of his career, expect Bryce's numbers to move towards the other guy. I'll guess the OBP and SLG drop, but he has decent shot at 160+ more HR over his contract. Of course, the other guy was a BALCO boy, so that hurt his candidacy, too, but he was mostly done in by aging poorly. Only a 1 time MVP.
