BIO: Full-time starter the past two seasons playing three different positions on the offensive line including both guard spots and left tackle.
POSITIVES: Big, physical lineman that easily handles one-on-one blocking assignments. Quickly gets into blocks, strong at the point of attack and drives defenders off the line. Anchors in pass protection, displays a nasty streak and works to finish blocks. Mentally alert, patient and helps out linemates. Seemed to improve all areas of his game as a senior.
NEGATIVES: Lazy with his fundamentals, not a natural knee-bender and gets tall. Gives inconsistent effort at times.
ANALYSIS: Flashing dominance on occasion, Herrera is a powerful blocker yet is not known as a hard worker off the field. If he puts forth the effort can start for an NFL team.
