For the most part, the NFL still values left tackles over right tackles. The blocker who can best defend a right-handed quarterback's blind side makes more money than one who holds up the quarterback's vision on first-read throws on short drops.

According to Over The Cap, eight left tackles are currently averaging $12 million or more per season. Philadelphia's Lane Johnson is the only right tackle making over $10 million.

Value, however, doesn't always completely equate to importance.

If your offense is heavily dependent on right-handed power running and quick passes based on front-side route concepts, the left tackle's defensive assignment won't have time to get to the quarterback on certain plays, putting the right tackle under more pressure. The Kansas City Chiefs and Philadelphia Eagles each feature concepts in which their ideal quarterback combines designed mobility and option concepts, and their right tackles—Mitchell Schwartz and Lane Johnson, respectively—are their best blockers.

Why are right tackles relatively devalued? Positional traditionalism has something to do with it, as conventional wisdom dictates it takes more pure athleticism to play the left side than the right. Right tackles generally have less fluid and agile dropbacks and kick-steps through the pocket, although there are exceptions. Right tackles are generally better power blockers in run sets and run-action, too.

For the most part, the NFL's best right tackles combine strong pass sets with above-average body control and strength against elite edge-rushers, who often line up to face the right tackle play after play. Some could kick over to left tackle in a pinch. The Eagles' plan seems to be for Johnson to take over Jason Peters' left tackle spot in time.

NFL1000 Offensive Line Scout Duke Manyweather has watched and evaluated every right tackle this season, and he ranked them all based on the following criteria:

Pass Protection: 25 points. How does this lineman handle edge-rushers one-on-one? Can he ride a defender in an arc around the pocket? How well does he adjust to maneuvers such as end-tackle stunts? Can he adjust his placement for inside counters? Can he square up against penetrating edge-rushers, allowing his quarterback to make the quick pass?

Run Blocking: 20 points. Does this lineman pinch inside well to seal the edge? Does he have the power and leverage to drive-block consistently? Can he hit the second level and block his targets to free his running backs at linebacker depth?

Power: 25 points. Does he put his hands on the defender's numbers and push him back? How is his upper-body strength? Is he strong enough to one-hand his way through a block if a defender does something he doesn't expect?

Agility: 20 points. Does he have the agility and light feet to move through a blocking progression against a fast, aggressive pass-rusher? Can he block at the second level on screens and other short passes that require vertical movement? How is his footwork on sweeps and pulls? How quick is he off the snap to deal with whatever's in front of him? Can he regroup after a missed block to clean things up?

Position Value: 10 points. This takes into account positional importance when comparing scores to other spots on the gridiron. Right tackles are given 8/10 points across the board, leaving them with a maximum score of 98/100.
