Training camp and the preseason games can be tough for fans to gauge. And history has shown that a teams win/loss record in the preseason doesn't always correspond with a similar record in the regular season.
However, one constant throughout every training camp is the opportunity for surprises.
They may come in the form of a veteran finally playing up to his potential. Or maybe it's a veteran who hasn't lost a step and in fact looks better than ever. Or maybe an unknown rookie like Terrell Davis (pictured) begins to show flashes of future stardom.
Once the preseason games begin it will be easy to place our focus on the end result.
Did they win?
But look a little closer. There may be some future stars out there.
Here are five Denver Broncos that have been impressive in training camp so far.
Mitch Unrein has been a pleasant surprise on the Broncos defensive line so far.
A defensive tackle that played his college football just north of Colorado, at the University of Wyoming, Unrein may have found a spot on the roster. He was signed undrafted by the Houston Texans in 2010 and spent last year on the Broncos practice squad.
He has been turning heads in camp this year. In fact, Unrein has been taking some snaps with the starting defensive unit.
At 6'4" and weighing in at 291 pounds, he has decent size but not much athleticism.
But just watch how hard he works.
Mitch was a walk-on at Wyoming from Eaton High School. He finished at Wyoming as an honorable mention recipient All-Mountain West Conference.
This is a real life Rudy.
Mitch Unrein may be a hometown boy who just drove down I-25 to Denver.
Tyler Grisham's path has been a little tougher.
Grisham played his college football at Clemson but went undrafted and was signed by the Pittsburgh Steelers in 2009. After spending time on the 2009 practice squad he ended up actually seeing game time and catching a pass against the Baltimore Ravens.
He was added to the Steelers practice squad again in 2010. Then they cut him.
The Steelers picked him up again in 2011. And then they cut him again.
Now Grisham is in Denver and his play has raised a few eyebrows.
He runs solid routes, has very good hands and he he isn't afraid to go over the middle. He has made a few impressive catches in training camp so far. He could add some depth to a wide receiving corps that sorely needs it.
Rahim Moore is having himself a very good training camp.
After being plagued by injuries and inconsistent play there were more than a few doubters (myself included) as to whether Moore could be the answer at safety.
So far Moore is proving the doubters to be wrong. He looks like a man on a mission.
Moore has all of the tools to be a very good safety in this league and last year there were flashes of what could be coming. Moore started in seven games last year and played in 15, but the game seemed to be moving way too fast for the rookie.
So far in training camp he seems to be ahead of the learning curve. And he's playing against a much better offense.
Moore could be key in a defensive backfield that needs more consistency.
Danny Trevathan was the Broncos' sixth-round draft pick out of Kentucky in 2012.
And while many sixth-rounders are hard pressed to even make the roster, Trevathan is actually contributing.
In fact, Trevathan is getting snaps with the first unit.
Coach John Fox has plugged him in ahead of Wesley Woodyard and Danny hasn't disappointed. An undersized linebacker at Kentucky, he is a player with a ton of speed and a motor that doesn't stop.
The linebacker position is one that must improve if the Broncos are going to be better defensively.
Trevathan is been a nice surprise so far. Keep an eye on him.
This is the guy that has been the talk of training camp so far.
Obiozor is making plays every single day.
A defensive end out of Texas A&M, Obiozor signed with the Packers in 2009 after going undrafted. He was cut by the Packers the following year and signed by the Cardinals in 2010. After being placed on the practice squad the Chargers signed him away but then cut him in 2011.
Right now he has the look of a player who is going to make those teams regret letting him go.
He is getting to the quarterback and he is closing down running lanes and swallowing up ball-carriers. Obiozor has been largely unblockable in camp.
Now the big question is will it translate to games?
We should get a hint on Thursday.
