After rookie minicamp, OTAs and the mandatory minicamp in June, the Kansas City Chiefs have done plenty of work in shorts this offseason.

But they get back to real football on Monday.

The pads will be on for the first time at training camp as the Chiefs prepare for the 2015 season with their first preseason game coming up in a couple of weeks against the Arizona Cardinals.

Monday's practice begins at 8:15 a.m. and is open to the public. You can find all training camp information at KCChiefs.com/trainingcamp.

While fans look forward to hearing the familiar sound of pads popping from their favorite players, the guys out on the field are looking forward to it as well.

Coach Andy Reid

"I'm looking forward to it. That's always a good time. You measure some of the young guys because some of the veteran players I already know about. The young guys I haven't seen in pads, I'm curious to see them. It won't all happen in one day.

QB Alex Smith

"It's been seven months since the last time I strapped the pads on. Even though we don't get hit as quarterbacks, it does changes things obviously. From a throwing standpoint, the shoulder pads change it up but it's really good work with the pocket and the offensive and defensive lines will be going at each other. For us it will be great pocket awareness work. We drill that stuff all offseason with movements and all the different types of escaping the pocket and things like that. It will be a chance for us with live plays to put some of that stuff to work. Before without the pads you don't always get those looks.

"It'll be fun. The defense will have to honor the run for the first time in a while and we'll get some balanced looks, so it'll be nice to get back to real football."

CB Sean Smith

"I can't wait. It's fun to come out here and run around without pads, but once they come on, it's a whole other ball game. The physicality of this sport definitely tests your technique and everybody's limits. You can't just run by somebody. Receivers have to really avoid you, because nobody wants to get pressed like that and it'll mess up their timing. It also lets me know where I'm at personally.

LB Justin Houston

"That's what you live for and that's what you work for during the offseason, that first day of pads. It's like Christmas to us."

LB Tamba Hali

"I'm excited. It's been a while and also when you put the pads on you kind of learn where you are physically with how you're moving around the field. It's been a long offseason and you want to see where you are. A lot of guys can do a lot in shorts but the game is a physical game."

OL Eric Fisher

"Let's just say I'm looking forward to this year. It's going to be a big year for me and for this team. Just the environment around the locker room and the practice field, we're going to do big things this year."

RB Jamaal Charles

"I'm excited, man. Because that's when you get to see who's really doing what, who is working. That's the only way you can tell about our sport, you can't tell anything in shorts because everybody looks good. It's about who looks good in pads."

TE Travis Kelce

"It's been an anxious ride this entire offseason. Football isn't football until your put on the shoulder pads, the helmet and those thigh pads. It's all a process and we're working towards being the best team we can come Week 1 and from there working to be Super Bowl champions. It's going to be fun."

WR Jeremy Maclin

"I'm excited about it. It gives us a chance to do the physical part of it, working on releases at the line of scrimmage, something that the younger guys haven't done yet. I think it's my job to kind of show them, encourage them and show them some techniques and stuff like that. But even for myself, it's been since December since the last time I really played so to be able to put the pads on and get hit a little bit will be good for me."

Rookie LB Ramik Wilson

"It's going to be fun. I'm just ready to go. That's all I can say."

DL Mike Catapano

"I can't wait. I have a whole year of bent-up frustration and I'm ready to unload out here. I just can't wait. I'm counting the seconds."

DL Mike DeVito

"It's huge for me because everything else has just been gym class. To get back out there and to get the pads on and see where I'm really at, I'm excited for that."

OL Ben Grubbs

"Contact. If you don't love contact then this isn't the sport for you. That's the one thing I'm really looking forward to, and to see how much my work paid off. We worked really hard throughout OTAs and minicamp, and to transition that over to pads is something I'm looking forward to."

LB Derrick Johnson

"I can't wait to throw the pads on. I'm a linebacker so it's exciting to get that contact going. I know it's not going to be perfect because I've been out of football for a while, but the quicker I get it on the quicker I can get back to form."

FB Anthony Sherman

"That's when you can finally tell where there's a football player and where there's not. The pads are what we play this game in and if you're a football player, then you look forward to the days you can put the pads on."

OL Eric Kush

"It's fun, man, I'm excited. Just to get out there and hit a little bit. It will help the team gel a little bit as we go out there and kick a little but."

OL Zach Fulton

"I'm looking forward to it a lot. It's going to be pretty fun to go out there and relieve some stress that's been built up over a while. It's going to be great, I'm excited."

Rookie TE James O'Shaughnessy

"I'm very much looking forward to it, but I think that's when you are really going to see the speed of the game, the tempo of the game and the physicality of the game change. That's when we really get to play NFL football. So, I would say I am extremely excited to see what that is about."

Rookie CB Steve Nelson "I'm very excited. I can finally get my hands on some guys and that's when the real competition out there happens."
