There are two sides to working with the first team as a rookie. First, you get to test yourself and compete with the best your team has to offer. The other is a bit starker: Any mistake is far more likely to be exposed when practicing next to guys who don’t make many of them. Michael Bowie, Seattle’s seventh-round draft pick this year, got a taste of both this week. Breno Giacomini, the Seahawks’ starting right tackle last season, was in New York for tests on a bothersome knee that won’t require surgery. That elevated Bowie to the first team for a week during organized team activities. “I feel like I held my own,” Bowie said. “I could have done a lot better in some places, but it wasn’t just horrible. Taking strides.” Bowie could potentially have a substantial role with the Seahawks this year. Giacomini has a firm grasp on the right tackle position and All-Pro Russell Okung is one of the game’s elite left tackles. But the position lacks depth. Of the guys currently on the roster, the most likely backup options are Mike Person and Bowie. Person, 24, is in his third year out of Montana State. He drew praise from coach Pete Carroll for gaining 10 pounds this offseason, but he has yet to play in a regular-season game. Bowie enters his first year as a pro with an interesting back story. After a two-year stop at a junior college, Bowie became a part-time starter for Oklahoma State as a junior in 2011, the year the Cowboys won the Fiesta Bowl. He was thought of as a key returning piece the following year. But Bowie was dismissed from the team for violating team rules; he has declined to talk about the situation.
