The main question has been how Kelly's spread offense will operate at the pro level and if he has the players to do it.
Is it possible for Kelly to be successful in year one at the NFL level?
Kelly comes into a Philadelphia Eagles franchise that is coming off its worst season since 1998. They finished with a 4-12 record and finished dead last in the NFC East Division.
With Kelly's new innovative offense finally hitting the NFL and him being with an underachieving team that has talent, the city of Philadelphia could be in for a fun first season of the Chip Kelly era.
The Eagles may not be a title contender, or win the NFC East for that matter, but they have a chance to improve after last year's disastrous season.
Here are five reasons why the Eagles will find success in year one under Kelly:
Eagle starting quarterback Michael Vick.
If there was a quarterback that Chip Kelly needed for his offense, Michael Vick would be it.
Robert Griffin III and Cam Newton are other starting quarterbacks in the NFL that could run Kelly's high-tempo offense, but jobs with the Washington Redskins and Carolina Panthers were, sadly, occupied. Colin Kaepernick and Russell Wilson would be in this discussion as well, with their ability to run the football.
Kelly was left with the decision of heading to Philadelphia.
It will be interesting to see if Vick can run this type of offense in the NFL, but there has been so much made out of what Michael Vick can and can't do as a football player anymore.
The 32-year-old Vick signed a one-year contract with the Eagles last Monday and will at least be guaranteed to play one-year under the Kelly offense.
Vick is capable of carrying the football and is still a solid passer. The question is going to be if he can handle the punishment of running this type of offense for the entire season. Even with Kelly tweaking the offense up a little bit to fit the NFL, his body is still going to take a beating.
If Vick does not suffer anything critical, such as a concussion or rib injury that keeps him out, the Eagles could potentially be much better this upcoming season.
New Philadelphia Eagle Head Coach Chip Kelly.
It's no secret that Chip Kelly is not your average football coach.
His innovation running the fast-paced offense with the Oregon Ducks changed the college football landscape. Defenses were not able to keep up a majority of the time and Oregon would put 40 or more points up on an opponent in a blink of an eye.
Kelly has a way of doing things that is completely unorthodox. He runs a different style of practices that every other team does not run.
The players run and play faster during practice than they do on game day. His offense requires a different type of quarterback than most NFL teams need.
Dixon expects to compete for the starting job against Michael Vick, Nick Foles and Trent Edwards. He has an advantage because he's run this offense before, unlike the other three. His chances of starting are very slim, though, strictly because of Vick.
Dixon has started only three games since he entered the league in 2008.
Being from the East Coast, specifically Dover, New Hampshire, Kelly has ties to that part of the country and will fit in perfectly with the Philadelphia culture.
He is strictly business and doesn't like to deal with the media a majority of the time. Kelly somehow always manages to say something comedic to the media, though. He entertains using very few words.
He can handle the pressure of this high profile job and has his own way of doing things. He wants his offense to be in go mode at all times and wants a strong and physical defense to go along with it.
I'm sure his motto "Win The Day" will be part of Eagle nation now.
Starting Philadelphia running back LeSean McCoy.
Chip Kelly is fortunate that he comes into a situation where he has running backs who can run this type of system.
In LeSean McCoy's fifth season with the Eagles, he will have even more pressure to be lethal in the Eagle backfield. He is a quick and physical runner that will be valuable in the spread offense.
We know McCoy is capable of doing a lot of damage on offense, as he rushed for over 1,000 yards in both 2010 and 2011. He managed to put up 840 yards last season, even after missing time with a concussion injury.
Backup running back Bryce Brown has speed and will also look to be a a factor in this new Eagle offense.
In a spread offense such as this one, multiple running backs are needed. Last season, Brown stepped in when McCoy was hurt and finished the season with 564 rushing yards and four touchdowns.
McCoy and Brown are going to be what makes the offense go.
With the pace of the play calling that will be happening, it is going to make it that much more difficult to defend this duo in the backfield.
Philadelphia Eagles wide receiver Jeremy Maclin.
The Eagle receiving core is going be crucial in opening up the Eagle rushing attack.
Jeremy Maclin is becoming more and more of a threat to defensive backs every year. Last season, he led his team in receiving yards and touchdowns. Maclin ended up recording 857 receiving yards and seven touchdowns.
Jackson is among one of the fastest players in the NFL, and has been given the opportunity to play in the fastest offense in the NFL.
The tight end position will be solid as well with physical veteran Brent Celek. Celek will be useful in the offense when there are quick passes up the middle.
Jason Avant will also be included in the passing game, as he recorded 648 receiving yards last season.
Chip Kelly has brought in a new staff, including new offensive and defensive coordinators.
Shurmur went 9-23 with the Browns.
He has a lot of experience under his belt and was with the Eagles coaching staff from 1999-2008, which was one of the best runs in Philadelphia Eagles history.
He was a tight end and quarterback coach during his tenure with the Eagles.
People have the right to question the hire based on his recent track record.
He lasted just one season both times at the defensive coordinator position and moved on the following year to new teams as a linebacker position coach.
The Eagles' defense is going to be a mystery in the months leading up to the 2013-14 season.
On the other hand, Kelly seemed to really hit it off with Davis, so we'll see what happens.
Davis will most likely switch to a 3-4 defense scheme, and there are questions on whether cornerbacks Nnamdi Asomugha and Dominique_Rodgers-Cromartie will still be with the Eagles when the season starts.
An interesting move that Chip Kelly also did when hiring was bring in five of his assistant coaches from Oregon, such as defensive line coach Jerry Azzinaro.
Bringing in his assistants from Oregon will make for a smoother transition with the Eagles, because these Oregon coaches will know what Kelly is talking about and what he expects.
