"When he was a toddler, it was hard for me to deal with the fact he had Down syndrome," Stacy said. "I didn't know what it was, I didn't know why he was acting that way.
"I remember the day my Mom sat me down and talked to me about his condition, and how she needed me to step up and help out from the man-of-the-house standpoint."
There were many days while Stacy's mother Barbara worked late that Stacy made sure his younger brother was fed.
"I remember working out on weekends, and just taking him with me," Stacy said. "He would be my spotter on the bench (press.)"
Justin had such a profound effect on his older brother that when Zach signed with
Vanderbilt, he discovered the school has one of the best special education programs in the country.
"When I found that out, I immediately pursued special education as my major," Stacy said. "I've learned a lot so far. I'm always calling my Mom to let her know what Justin needs.
"I've been around him so long now that I forget he has Down syndrome. He acts like a normal kid, outside playing and running around, tagging along with his big brother. He comes to most of the games. Seeing him after the game, win or lose, with his big smile is heartwarming."
So any time Stacy has a weak moment and feels sorry for himself when things aren't going exactly right, the moment quickly passes.
"Justin has taught me you can't take life for granted, and that goes into my football," Stacy said. "(Vanderbilt) Coach (James) Franklin always emphasizes to play every down like it was your last. Because of Justin, that's the mentality I've taken ever since I started playing this game."
