If they had the top pick, the intelligent thing would be to measure what they could get for that pick, plus what they believe Dart will be vs what they could get for Dart, plus what they believe Mendoza will be.
That aside, they could have gotten a fortune (two, maybe three firsts, depending on how high a pick the highest first was; and second, a third & a fourth).
We could have filled out the secondary, defensive line and offensive line with the haul, and added an offensive weapon with our second round pick and more depth with the rest of our picks.
Oh well, ownership was planning on bringing Schoen back anyway so I'm not sure he would have done enough with the picks.
