The Kansas City Chiefs took the field on Saturday afternoon in front of a crowd of more than 4,000 fans, all of whom waited through long lines and some early rain to catch the first opportunity to watch their favorite players prepare for a season full of optimism.
And there's plenty of reason for all that optimism.
Under the leadership of head coach Andy Reid, the Chiefs have put together three straight winning seasons and two playoff appearances, including the first playoff win in more than two decades last year, and heading into 2016, the players understand the opportunity they have ahead of them.
They know they're good and capable of achieving goals that haven't been attained in this organization for some time. The players don't shy away from this adulation, but they understand there's work to be done in order to achieve what they haven't yet been able to accomplish.
The continuation of an offseason full of hard work took place on Saturday on the campus of Missouri Western State University.
Here are five observations from the Chiefs first full-team practice of training camp:
1. Chiefs Kingdom came out in full force
Within minutes of the gates opening before practice, all of the spots along the fence nearest to the field were completely taken by excited members of Chiefs Kingdom. The hill on the north side that overlooks both practice fields quickly filled up as well.
For the first 20 minutes, the fans had to try and stay dry as rain fell through player warmups and briefly into individual drills.
Once the rain subsided, the fans saw about an hour and a half of a practice that wasn't short on highlights or great moments.

The fans who got there early were also able to get the best spots for player autographs that took place at the conclusion of practice.

2. Four players who have reported to camp did not practice on Saturday
When Reid spoke with the media after practice, he explained that running back Spencer Ware didn't practice on Saturday because he was sick.
The Chiefs currently have three players who reported to camp but are on the Physically Unable to Perform (PUP) list, and they also did not practice on Saturday.
Those players are running back Jamaal Charles and linebackers Justin Houston and Tamba Hali.
All three players count towards the 90-man roster right now but can be pulled off the list at any time and begin practicing or playing immediately. If they aren't taken off the PUP list by the first regular season game, they will have to miss the first six regular season games.
It's something to monitor as we work our way through the preseason.
The Chiefs also made a corresponding roster move after the hamstring injury on Thursday to cornerback Tre Jones.
3. Rookie continues taking key reps along offensive line
When the Chiefs offense took the field on Saturday, the left guard spot was once again held down by rookie fourth-round pick Parker Ehinger, who had been playing that position through OTAs and minicamp back in June.
"The goal is to get some playing time," Ehinger explained on Tuesday. "Whether I'm starting, or the six-man or the swing guy or whatever—obviously that doesn't come from my decision—that's up to coach Reid and (offensive line) coach [Andy] Heck. Wherever they need me, I'll be happy to play wherever.
"I'm just hoping to get some playing time this year."
While Ehinger admitted back in June that he knows starting spots aren't handed out in the offseason, the fact that he's still in there is a good sign for him.

4. The guys on the defensive side of the ball made some plays on Saturday
Both Steve Nelson and Marcus Peters had interceptions during 11-on-11 drills on Saturday that resulted in touchdowns for the defense.
Nelson, who earned the starting nickelback position coming out of OTAs and minicamp, jumped in front of a Tyler Bray pass that was intended for rookie receiver Tyreek Hill.
Nelson fought his way to the ball and snagged it out of the air before going the other way with it.
While interceptions have become a regular thing for Peters, the pick he had on Saturday was a thing of beauty.
In some ways, it looked similar to the play he made against Peyton Manning and the Denver Broncos last season, when he undercut the route and had a clear lane to the end zone.
Peters looks to follow up an impressive rookie season in which he was named the NFL's Defensive Rookie of the Year, and Saturday was a good start.
5. Travis Kelce gets involved in quarterback accuracy game
During one portion of practice, tight end Travis Kelce went over and joined the quarterbacks who were on the other field competing in a game of accuracy.
Here's what that looked like:
