The team losing the player has to have offered the player arbitration before drft picks become involved.
If the team losing the player drafts in the first half of the draft, they lose a second round pick instead of a first round pick.
Following the '99 season, Tampa Bay signed both Guzman and Vaughn. The Reds didn't offer Vaughn arbitration, so the Reds didn't get a pick for losing him. Tampa Bay drafted in the upper-half of the first round, so the Reds got their second round pick for losing Guzman.
