This feels more like a scenario to me than a projection -- if Houston takes someone else at No. 1, then most of the picks succeeding it will change as well, and as of early Thursday it did not appear that the Astros had decided on their selection.
As of now, this is my best projection for the top 33 picks in the draft -- the formal first round, plus the six compensatory picks that teams received for losing free agents who received qualifying offers this offseason. I'll add relevant info and buzz as it comes in throughout the day.
