Im willing to bet Russell Wilson thought he should have been the #2 QB taken in his draft perhaps only behind Luck. He was 6th of 11 QBs drafted in what would be a very strong class had RG3 not flamed out and if Kelly's system didnt ruin Foles much like Martz did to Bulger.
However, Adams is not the same athlete, nor as proven as durable as Wilson. Wilson and Tannehill are the only QBs to start every game over the past 4 seasons. I feel what makes Wilson more remarkable is the type of defenses Wilson has faced in comparison as well as 10 post-season starts.
Adams is a good player though. He was successful at EWU and very good in the Pac-12. I think he would he flourish as a backup, getting his body right, and soak up Wilson like a sponge. But I wouldnt want him until the 5th-7th rounds.
The only QB id want before the 5th that would be obtainable is Dak Prescott. However, id take a flyer on Cardele Jones, Kevin Hogan, or VernonAdams in the 5-7 rounds.
