I agree with the wise @BusterD.
With 20 guys off the board, there’s still some value keeping Dak in the 10th. …mayyyyyybe Gore in the 5th, but that’s depending on who all else is kept by other teams.
…It’s also worth asking what your draft position is. If you have a late pick (9 - 12), then you’re always getting more value out of keeping guys in odd-numbered rounds. Whereas if you have an early pick (1-4), then even rounds are where you get the most value.
(For example, Evans is a huge value in the 2nd round if you have the 1st overall, because you’re getting him for the 20th pick.)
With that in mind, if you can trade draft picks and players, DO IT. If, for example, you have a late 1st round pick, see if you can get another keepable player from a team by trading your early 2nd round pick for their late 2nd round pick. It costs you nothing because you’re keeping Evans in the 2nd round, regardless of which 2nd round pick it is. And you get another option. Or a better draft pick elsewhere – like swapping early for late 2nd… but then late for early 3rd and 5th.
A lot of variables there, but hope it makes sense.
