Grogan was known for his toughness. He played hard for 16 years despite suffering a variety of injuries that included five knee surgeries, screws in his leg, a cracked fibula, two ruptured disks in his neck (which he played with for over a season), a broken left hand (he instead handed off with his right hand), two separated shoulders on each side, the reattachment of a tendon to his throwing elbow and three concussions.
But the modest Grogan will say he only suffered "a couple" of injuries while in the league. For him it wasn't a matter of being tough it was a matter of going out, earning his job and doing what he loved to do.
"I just loved playing football and I loved the game," he said,. "Also, in the back of my mind I knew if I took too much time off somebody else would come along and scoop up my job and I didn't want that to happen. I played through injuries the best I could when I was hurt. I just had to fight through a lot of things, but it wasn't that difficult."
