The funny thing is the teams that spend the most and stuff their rosters haven't had much luck in the postseason though they do tend to get to the postseason. Except for the Angels. lol Baseball can be so unpredictable. Nobody would have guessed the Houston Astros would become a perennial powerhouse after years in the cellar losing 100 plus games. They're not a sexy free agency destination. They rebuilt that organization from the ground up. You look at what the SF Giants did in their trilogy championship era without having to spend a fortune on big names. How about the 2014 and 2015 Kansas City Royals?
It's never about individual greatness. It's about having a complete team with strength in every area of the game. And being able to sustain it until the last out of the WS. But you never know at the start of the season unlike other sports which set of players will be able to do that.
