MANKATO – Vikings tackle Matt Kalil hardly hears a peep from rookie guard David Yankey.
"He's a quiet guy," Kalil said.
You won't hear Yankey say much. You won't catch him joking around at practice. He won't clog your Twitter timeline with 20 tweets a day.
For a rookie, that's not a bad thing. Yankey is going through the process of breaking out of his shell and adapting to a new locker room, like he did at Stanford. The same could be said on the field as well, where Yankey hopes to find a role on a veteran-led Vikings offensive line.
Yankey hasn't received first-team reps at left guard during training camp, and that won't be in Vikings coach Mike Zimmer's future plans. Yankey is expected to initially back up Charlie Johnson, who has started at left guard for the Vikings over the past three seasons.
"He's unquestionably the first-team guard," said Yankey, who continued to receive second-team reps in Saturday night's practice. "I'm just learning from him as much as possible. He's a great player, very underrated, really technical; one of the oldest O-linemen and a lot of respect for him."
While Yankey, listed at 6-6 and 315 pounds, already possess a bigger frame than Johnson, 6-4 and 305, Yankey missed most of Vikings' organized team activities because of an NFL rule that barred a draft pick from participating in OTAs until after he completes his finals. Stanford operates on a quarter system and its spring finals are in mid-June.
Yankey caught a red-eye flight once he completed his finals to participate in the final three OTA sessions, but he missed a considerable amount of time learning technique, including improving his pad level, hands and feet. Yankey said he must specifically improve his body position and avoid leaning on defenders.
