The 2012 NFL Draft moves into the 2nd and 3rd rounds where there are lots of good players remaining. The first round is filled with the superstars while the 2nd and 3rd rounds are usually considered solid starters.
For teams looking for offensive line help, there are a number of quality offensive linemen remaining, including the best center in the draft.
Wisconsin C Peter Konz was a first round pick in plenty of mock drafts so he's a candidate to go early in the second round. Konz is arguably the best center in the draft.
Stanford OT Jonathan Martin was also commonly sent in the first round of mock drafts so I'd expect him to be off the board early on Friday night. Ohio State OT Mike Adams was also a first round pick in some mock drafts. Iowa State OT Kelechi Osemele can play offensive tackle or guard and should be a second round pick.
Midwestern State G Amini Silatolu is a small school prospect who drew some first round interest.
