The SEC had 91 former players on MLB Opening Day Rosters, with the ACC in second with 47.
Anyone who says the SEC isn't the best college baseball in the land is just flat out lying.
Also, 46% of players on MLB Opening Day Rosters went to a 4 year college, and 5% went to at least a 2 year college, So you have 51% of players on Opening Day Rosters having attended college of some sort.
So parents - send your kids to college. Hate to break it to you but you're not raising the next Bryce Harper.
