Cubs and Astros tanked.
They aren't small market.
The O's have hit on some guys, and missed on a lot of others. Guys like Pearce jumped from team to team only to have a huge breakout season for one of them.
Does the top pick in the Rule V draft have better odds of being a successful major league players than the guy picked fourth? No idea, but if I had to guess I'd say there isn't much difference.
Remember Wells was picked in the second round of the Rule V draft, anyone remember who was picked by the O's before him?
