If Adams comes back next year, then Iowa really only loses their shortstop (Mccoy) and a starting pitcher (Erickson). They had a lot of injuries to their pitching this year that hopefully bounce back next year.
The key will be Adams coming back. I have no idea where he's at on that. Some projections I've seen had him in the top 10 rounds back in early May. I'm sure that has only increased over the last few weeks.
