Here's an insightful article about how left tackle, once considered part of the "Holy Trinity" needed for a championship team, is now largely unessential.
Because of the shift to quick release passing games, interior linemen are more important.

...more teams are utilizing precision passing attacks that require quarterbacks to get rid of the ball much faster than ever before. With clubs using variations of four-receiver and/or two-tight end sets, quarterbacks don't necessarily need their linemen to hold their blocks as long.
Increasingly, teams are devoting more resources at guard to keep the quarterback from getting rushed quickly up the middle.
"The pass rush is more about straight lines now," New York Jets coach Rex Ryan said. "In the past, you would loop an end inside, take a longer route, to confuse the blocking scheme, but you don't have time for that now. It's get there and get there fast."
Ryan's approach is a great example. Many of his best pass-rush schemes are "overloads," where he may only bring three or four rushers, but they all come from the same side of the offensive formation.
The Patriots are a great example of how protection is now focused on the middle of the line rather than the classic "blindside" protection led by the left tackle. New England's best offensive lineman is Pro Bowl guard Logan Mankins, who teamed with veteran Brian Waters on the inside. New England suffered most on offense last season when it was forced to replace injured center Dan Koppen. Tuck indicated there's an obvious reason for that.
"The time we kept Brady in the pocket and didn't allow him to step up, that's when we had the most success against him," [Justin] Tuck said. "Now, that's any quarterback, but it's especially [true of] Brady. All he needs is one step. Not even one step, just be able to plant that front foot and deliver and he's a different quarterback.
"You can rush him off the edges all you want and he'll slide and step forward away from that. You have to have forward pressure in his face."
