Also, most coaches will tell you that the defense is always ahead of the offense early in the season, and that the last piece of an offense to come together is usually its pass protection, because of the required unison between several players.
Geoff Schwartz, a seventh-round draft pick out of Oregon in 2008, played eight seasons in the NFL (including two with the Giants) and recalls needing a few months as a rookie to master his three-point stance, and then having to re-work it in the offseason with the help of veteran teammate Jordan Gross. But he was on the practice squad his first season, so he had time to adjust.
"In college, there is so much misdirection, and the tempo is so fast at times, you don't even have to really block anybody because the defense is so tired," Schwartz said. "What we've really lost in college is the idea of finishing. In the NFL, you have to finish to be an elite offensive lineman. In college, your goal is to get back to the line of scrimmage and snap the ball again. The mentality of not finishing in college hurts you when you get to the NFL."
Nick Hardwick, who played 11 seasons as the Chargers' center before retiring in 2014, suggests another theory for the decline in play. "I've talked to some nose tackles and defensive tackles around the league who say the craftiness from offensive linemen is dissipating," he said. "Guys understand the basics of the game—hat placement, eye placement, footwork, hands—but they don't understand the nuances that take their game to the next level. The subtleties of having a personal game plan for how to set up your opponent, so you are not countering his moves, he's countering yours."

Well come to think of it, he does have the coaching chops, I mean he's played in man blocking and now he's doing fantastic in zone blocking. Coach Monte Clark (former 49er OLineman) was HC here in '76 and a lot of the '81 OLinemen were either acquired by him in '76 or developed by him in '76 before McKittrick got on board in '79. I"m thinking Coach Staley - having played both styles, would be a great coach for Kyle, should that ever happen.
