Fast forward nearly five months, and Adongo is a blur racing down the field in a blue jersey at the start of special teams practice. When he signed with the Colts, he weighed about 235 pounds and his diet consisted primarily of fruits and nuts.
Now, Adongo is a chiseled 270 pounds and a more than imposing presence on the field.
"The guy couldn't even put his pants on six months ago, didn't know how to get into a stance, knew nothing about football and look at where he's at now," defensive end Cory Redding said. "He's giving the offensive line fits (in practice). He's strong, he's fast, very aggressive player, and I cannot wait to see him line up wherever they put him. Whoever's across from him is going to be in trouble. He's a heck of a player. You're all going to see it."
Adongo's most likely starting point is on special teams.
That's where he was earlier this week, blowing past a coach's block and barreling toward a simulated ballcarrier. Adongo suddenly decelerates, so as not to make contact, and then hustles to the back of the line.
In rugby, he hit players all the time. But he's never gotten the chance in football because he's only competed in drills against his teammates.
That could spell bad news for an unsuspecting Bengals special-teamer today.
"He hasn't been on the field under the lights when it counts, but he's played on a big field before," Colts head coach Chuck Pagano said, referencing Adongo's rugby past. "He's ran around and tackled people before with no pads so I suspect, instinctively, he'll know how to do that. It might be even more physical and violent because he does have pads. Don't be shocked to see him knock some people around if he gets an opportunity."
