Except that the players we’re viewing as “marginal” is done so in a very limited context. Back to Trayce Thompson, who had a horrible 2018. He’s still a better player than most minor leaguers, and in many cases it isn’t close. And those guys are professionals too. Dan Butler, for example, should be the guy we look at as the true “marginal” player as opposed to, say, the Orioles’ roster.
And most of us played baseball at some point. And we probably all had that teammate who just flat out dominated and we thought should make the majors one day. But how many of those teammates did? And if he did, was he any good?
I had one teammate who made the majors. It felt like an obvious conclusion at the time. He was just soooooo much better than the rest of us, including the competition. And he did make it, and played for 14 seasons. As a bench player and pinch hitter, never once in 14 years of MLB did he have 300 plate appearances in a single season...
