Kingsley Eguakun, one of the dark-horse candidates to win the Detroit Lions’ starting center job in training camp, underwent an NFL rite of passage this summer. Eguakun gained “15 or 20 of those pounds” back — pure muscle, he said — and after merely holding on for dear life as a UDFA rookie last year, is hoping to earn himself a spot on the Lions’ 53-man roster. “I did it slowly, the right way,” Eguakun told The Detroit News. Eguakun, who played his entire college career at Florida, was signed by the Lions as a UDFA last offseason.
