Yes, i'm aware. What i'm saying is that it's silly to cap the medicals at top 10 or 15 when the top 15 is usually who you're trying to keep the medicals from.
And it discourages trade partners from being able to make informed decisions about a player above their draft position.
Say for instance that Steph was predicted to be drafted by Washington, but the Celtics wanted to trade their next 8 drafts to go up to get him. This arrangement gives Washington access to medicals, but not the Celtics. So maybe that trade doesn't get done as a result.
I know that's a longshot example, but it isn't really that far-fetched, especially given how prone some teams are to trading away bunches of picks when they identify someone they want.
The NBA loves the transaction cycle as much as any league. This discourages transactions, if even just a little bit.
