CLEMSON, S.C. (AP) -- Clemson coach Dabo Swinney had more than a few questions about his offensive line back in the spring.
Eight months later, the "union" has things under control.
The guys up front, dubbed the "union" by offensive line coach Robbie Caldwell, have been a pleasant surprise for the 11th-ranked Tigers (9-1, 6-1 Atlantic Coast Conference).
The line is led by fifth-year center Dalton Freeman and is kept the Tigers' high-paced attack on the move, opening holes for tailback Andre Ellington and providing solid protection for quarterback Tajh Boyd.
Few saw that coming last spring when Freeman and junior Brandon Thomas were the only returners from a group that lost five seniors from last year's ACC champions.
