The 49ers rounded out their 11-man draft draft by finding a swing tackle, Iowa State's Carter Bykowski, and a cornerback, Marcus Cooper from Rutgers.
The 49ers have plenty of depth on the interior of their offensive line after drafting Daniel Kilgore and Joe Looney the last two years. Tackle, however, is thinner. Starting guard Alex Boone would have had to move to tackle if there were any long-term injuries last year.
Like left tackle Joe Staley, Bykowski began his college career as a tight end and weighed 245 pounds when he played the position. He now weighs about 305 pounds and can play on either side of the line. He was a right tackle as a junior and played left tackle this past season.
Cooper, meanwhile, only was a part-time starter for Rutgers last season, and because of that he didn't expect to be drafted. "My agent said to come in with the mindset as a free agent, and if you get drafted take it as a blessing."
Still, he had an excellent showing at Rutgers' pro day last month, running the 40-yard dash in 4.43 seconds and adding a vertical leap of 39 inches and a broad jump of 10 feet, nine inches.
His size - 6-2, 192 - caught the attention of the 49ers, who have been sniffing around tall cornerbacks all offseason and who signed 6-2 Nnamdi Asomugha in free agency. "With the bigger receivers coming in these days, you have to have bigger cornerbacks," Cooper said. " And that worked to my advantage."
