Colts fans will need a roster to help identify the defense this season, which was revamped in the offseason.
The defense has undergone a major personnel overhaul. Free agents have arrived in Anderson from all over the NFL.
"It's night and day, man. We have the body size, the type of men that's built for this system, that's played in this kind of system," REDDING
The Colts spent $140 million on free agency in the offseason, a big chunk of that on defense. Colts owner Jim Irsay expects it to pay off.
Number 93 is not Dwight Freeney anymore - it's Erik Walden now. He started nine games for the Packers last season.
"We've got a lot of physical players, we've got players that can rush, cover. So, got a lot of variety that's going on to help the team get better. You've got to take your hats off to the organization for making those decisions," Walden said.
Number 59, linebacker Kelvin Sheppard, came to the Colts in a trade for Jerry Hughes.
"It's definitely a revamped defense and we think it's definitely for the betterment of this team and for this organization. The steps we've taken already this training camp has really been tremendous," said Sheppard.
In the trenches, 300-pound defensive tackle Ricky Jean Francois played in the Super Bowl with the 49ers last season.
"Defense wins championships, so everybody...you always got to have that defense to make sure we can hold...be the best thing in the NFL. When I kept seeing the signings of what type of players we kept getting, and just, like, you kept seeing the probably one of the best defenses in the AFC getting put together, like, right in front of you," said Jean Francois.
Add 20 more pounds for run-stuffer Aubrayo Franklin, a veteran pick up from the Chargers.
"Just a lunch pail guy. Come in, take double teams, let my linebackers run and make plays. As long as those guys make plays and we stop teams in the run, I think my job is done," Franklin said.
Every unit in the Colts defense is retooled. Cornerback Greg Toler from the Cardinals and safety LaRon Landry from the Jets give Colts fans two more new players to learn.
