Anyone who knows anything about football will tell you it's all about the line.

The glamor boys playing quarterback, running back and receiver — the skill boys — are the ones are fun to watch.
But it's the boys down in the trenches who largely decide most football games at every level.
The Class of 2015 will likely be known for its linemen, as six of the nation's top 10 recruits excel there, including the top three: defensive tackle
Trenton Thompson (6-foot-2, 313-pounds) from
Westover (Albany, Ga.), offensive tackle
Martez Ivey (6-5, 275) from
Apopka (Fla.) and defensive tackle
Kahlil Mckenzie (6-3, 354) from
Clayton Valley Charter (Concord, Calif.).
Thompson has committed to Georgia and McKenzie is headed to Tennessee. Ivey has yet to commit, but is largely leaning to the Florida Gators.
