The Buffalo Bills and Miami Dolphins boosted their offensive lines in the second round. With back-to-back picks, Buffalo selected offensive tackle Cordy Glenn and Miami selected Jonathan Martin, another offensive tackle.

Both teams had major needs at the position. Buffalo is looking for a left tackle to protect quarterback Ryan Fitzpatrick's blindside, while Miami is looking to fill the right side of its offensive line. Glenn will have a chance to compete for a starting job with left tackle in Buffalo. Martin now is the favorite at right tackle, opposite Pro Bowler Jake Long. Martin joins first-round pick and quarterback Ryan Tannehill in Miami's 2012 draft class.

Glenn and Martin should help both teams right away. Wide receiver is still a big need for the Bills and Dolphins, so look for them to address that need in the later round.
