Actually that isn’t true anymore. It was more true in the Jim Wells and Bertman Days, but not so true now. I really don’t want to get into NS, but let’s just say back in Bertman’s day the economy was better, and some poor kid from Mobile Alabama could realistically live off a non guaranteed Minor league contract. Not so much today. Now you are seeing folks like Justin Smoak, dansby swanson, Josh Donaldson, Justin Verlander, Dallas Keuchel, and Alex Bergman who would’ve been in the MLB far sooner in Bertman’s hay day, but chose college over a minor league contract to get a guaranteed contract.
Unless you are looking at a generational player that is guaranteed millions to play minor league ball ( top 3 draft pick mostly) like Mike Trout, Clayton Kershaw, or Freddie Freeman, or a Japanese or Latin American all star, then about 80% of the MLB rosters are filled with players who attended college. Many pro scouts have said that playing baseball in the SEC is on par with playing AA ball.
fair points that don't contradict the general thrust of the argument I was making.
Bertman doesn't coach nowadays or in the last 17 years, so while I'll concede there's been a shift, 17 years in baseball is damn near TWO generations ago (closer to four if we go by the avg MLB career lasting 5 1/2 years).
