It's a personal experience, most certainly. I'd offer at least two observations, FWIW. One, great potentials are, and should be uncommon. Potentials grow over time, experience, and observation. One-stars do become three-stars now than then. Secondly, the AI's signing these players, too. Next time you run a couple of long-term sims, examine the top 20-25 players in both pitching and hitting in the league and I'd be surprised if not at least one of them contained a first line note in their history similar to "international signing from Venezuela by the Chicago Sox." Their success can creep up on you, both in the league and in your organization.
