|Each of the last four No. 1 overall NFL draft picks and 10 of the last 12 have been quarterbacks, but without a standout signal-caller available this year, the Kansas City Chiefs instead opted to acquire former top pick Alex Smith from San Francisco. Now they may choose to protect their new investment and bring in a potential longtime anchor for their offensive line, and Joeckel could join Orlando Pace and Jake Long as the only offensive linemen chosen first overall since the AFL-NFL merger. He certainly has the credentials to be the top tackle. After paving the way for Heisman Trophy winner Johnny Manziel's prolific offense, Joeckel earned first-team All-America honors as well as the Outland Trophy as the nation's top interior lineman. He helped Texas A&M rank third in the nation with 558.5 yards per game and the Aggies went 11-2 in their inaugural SEC season, highlighted by a road win over eventual BCS champion Alabama and a 41-13 rout of Oklahoma in the Cotton Bowl. Joeckel, who declared for the draft after his junior season, started all 39 games of his collegiate career at left tackle, and he should be ready immediately to help protect an NFL quarterback's blind side. With prototypical size and polished technique as a pass blocker, he also has the elite athleticism required of a massive tackle to stay in front of speedy rushers. Joeckel is effective in the running game, too, but that's not what would vault him to the top of the board. The NFL is a passing league, and the Chiefs may want a sturdy protector to give Smith the best chance possible to revive their offense, which scored fewer points than any other team in 2012.
