Joe Thomas was definitely one of the more dominant left tackles in the league right off the bat. Matt Kalil was a very dominant pass blocker, and while he isn't much of a road grader in the run game, he came in and played extremely well for a rookie. You asked who came in and played dominantly right away, and he did just that. This year doesn't have anything to do with his rookie year. Jake Long probably had the most struggles of all of them, but none of them conceded more than two sacks during their rookie seasons (Joe Thomas gave up zero in 10 games and only 10 pressures, Jake Long gave up two and 15 hurries in a 16 game season, and Matt Kalil gave up 2 and 19 pressures in a 16 game season, while also helping to block for AP's MVP season). How is that trolling to ask a serious question? You're tossing out several names, so I want to know how you define elite. Your list is pretty long.
