The 1965 draft had a major league and AAA section (rounds 1-3), a AA section (4-7) and A-ball sections (8+). Each team had one pick in rounds 1-7 (MLB, AAA, and AA picks). Starting with the 8th round teams received a pick for each A-ball team in their system in the reverse order of the affiliate finishes. Franchises that shared affiliates, alternated the picks round-by-round. This means that a franchise will have multiple picks in a "round". For presentation reasons here, we have re-labeled the rounds to be the number of the selection made by this franchise. This means that the Twins' 10th round pick could come after the Mets' 12th round pick.
Indeed, data is more important to every team now than it was in 2002. Not only do teams dig deep into college stats, like the Moneyball A's did, but they have access to advanced TrackMan data from showcases and tournaments, or they have medical coordinators charting biomechanics and workloads. They have analytics departments that put that data into historical perspective. Some scouting executives are coming from the internet's analytical community . The result of all this data appears to be, broadly, a confirmation of what scouting wisdom had been: Good major leaguers usually do make good jeans salesmen.
