The first time Mike Trgovac was introduced to Josh Boyd came prior to the 2012 NFL draft when the Green Bay Packers and their defensive line coach were looking at Mississippi State standout Fletcher Cox. As the calendar turned to April, however, the chances of Cox falling to the Packers at the No. 28 spot in the first round became unlikely — he eventually went 12th overall to Philadelphia — but all was not lost. While scouting the first-team all-SEC defensive lineman, Trgovac also began to notice Boyd, who registered 51 tackles (eight for a loss) and 41/2 sacks lining up next to Cox on the Bulldogs’ defensive line in 2011. When Boyd returned last fall for his senior year, the Packers kept tabs on his progress. Although his numbers weren’t as gaudy without Cox (33 tackles, 1½ sacks), they saw something they liked in the 6-foot-2½, 300-pounder. Enough it seems to draft Boyd with their fifth-round pick (No. 167 overall) last weekend, making him the ninth defensive lineman taken by general manager Ted Thompson since the Packers switched to the 3-4 defense in 2009. After weighing in at 310 pounds at the NFL scouting combine, he’s also the heaviest defensive lineman the Packers have taken in the draft since B.J. Raji four years ago. “I looked at tape this year, he’s obviously a big man,” Trgovac said. “He has some explosion to him. We think he has a little versatility to him as well. I’m going to see if I can get some nose (tackle) reps out of him. We’ll have to determine that when they get here.”
