Despite numerous top draft picks, including the number one overall pick in 2008, the Phins' O-Line remains a glaring weakness. There are not a lot of good options in FA, so we must improve through the draft. Lots of talk of us taking a WR in the first round, but our best value pick at No. 12 maybe an O-Lineman, especially if Chance Warmack (Alabama) or Eric Fisher (Central Michigan) were to fall.
This article provides an overview of the Top 20 O-Line draft prospects.
