Some teams subscribe to the "best player available" theory, with the Rams, Bucs and Browns clearly being among them.
Consider that the Rams, who invested the No. 2 overall pick in Jason Smith last year and only a few years back invested a first round pick in another offensive tackle, Alex Barron, made Rodger Saffold, a career tackle, the first pick of the second round. Saffold will most likely be moved inside to guard.
As talented as Saffold is, he doesn't fill the need for a defensive tackle the Rams now have considering they traded away former starter Adam Carriker.
On the opposite side of the spectrum, the Tampa Bay Bucs, who had a need at offensive tackle, instead elected to again fortify their defensive line, taking Brian Price from UCLA. His burst inside made him a natural candidate as a 3-technique, the same position the Bucs had filled previously with first round pick, Gerald McCoy.
The Browns made a similar move, electing to look past concerns at pass rusher and quarterback to take another defensive back -- the 10th among the first 38 selections. Pairing the big-hitting TJ Ward with first round pick Joe Haden and recently acquired DB Sheldon Brown gives the Browns an impressive new secondary to compete with the underrated passing attacks of the AFC North.
