In the life-in-the-fast-lane world that is the NFL draft, call it the year of the dump truck. This race will not go to the swiftest. The running backs, pass catchers and even the quarterbacks will have to make themselves comfortable before hearing their names called during the April 25-27 draft. It's the year of the big man — an exceptionally deep year for draft prospects on the offensive and defensive lines, two of the high-need positions for the Broncos. "If you're looking for players at those positions, this is probably the kind of draft for you," said Titans coach Mike Munchak, a Hall of Fame guard during his playing career. "You can find guys in the fifth, sixth and seventh rounds, guys where you say he's going to be our guard or center for the next 10 years." Some talent evaluators don't believe there is a quarterback who has earned a first-round grade, but they believe a total of 20 offensive and defensive linemen could carry a first-round grade. Texas A&M tackle Luke Joeckel could be the first offensive lineman drafted No. 1 overall since the Dolphins selected tackle Jake Long in 2008. Long was only the third offensive tackle selected No. 1 in draft history, following Orlando Pace in 1997 and Ron Yary in 1968.
