Adrian Clayborn was chosen by the Tampa Bay Buccaneers with the 20th pick last April. In 2010, the Green Bay Packers scooped up Bryan Bulaga with the 23rd selection. Reiff and Bulaga left school as juniors.
Reiff became the 19th first-round pick in Iowa history. He was the sixth Iowa player to go in the opening round since Kirk Ferentz took over the program in 1999.
The draft continues on Friday and Saturday with the second through seventh rounds.
