It's not surprising that the draft is looking different than many mock boards due to the lack of 2020 data to go off of due to the lack of games to evaluate.
Elias is clearly not afraid to go with a guy with one plus plus tool (power) which is a bit surprising for the #2 overall pick. His hit tool is probably plus as well, but the K-BB ratio prior to his short junior year makes him a bit of question mark when he has to face professional pitching on a nightly basis.

The way I see it, there's no immediate need to trade either Santander or Mancini. The O's have a lot of good prospects at AA and below, but they don't have any OF/1B types at Norfolk who are making a compelling case that they need to be called up. Maybe Yusniel Diaz or Johnny Rizer will force the issue later this season or next season.
You could make a timing argument that Mancini will never be more valuable than he is now, but I believe that he's a very good hitter who is likely to look like a very good hitter this time next year, or over the offseason. Trading Santander right now would certainly not be selling high.
