Greg Auman @gregauman · 32mLooking at position battles for Bucs in August, last offensive line spots are wide-open. 3 undrafted rookies, 3 2nd-year guys all have shot.Seems like Virginia Tech's Andrew Miller has strong chance w/ Bucs. Started at center & guard for Hokies, a key asset for backup o-lineman.Bucs also have Matt Patchan at tackle, Josh Allen at center as undrafted rookies. Figure they keep 8 offensive linemen, dress 7 each week.
