The winningest coach in Philadelphia Eagles history will take over a team that has had five different coaches since Reid took the job in Philadelphia. It will take a lot for Reid to lead a transformation with the Chiefs, who scored the fewest points in the league in 2012 and were 25th in points allowed. But the Chiefs aren't a total lost cause that needs to be completely blown up. On offense, the team has a playmaker at running back in Jamaal Charles, but receiver Dwayne Bowe is a free agent that will likely get a lot of interest this offseason in a pretty solid market for receivers.
Defensively, where the Chiefs have mainly struggled over the past few seasons, Derrick Johnson and Eric Berry are a good pair to build a franchise around. With the top overall pick in April's draft, there are plenty of directions the Chiefs could go. But honestly, trading the pick might make the most sense with a weak quarterback class (where the Chiefs desperately need a long-term solution) in order to simply stockpile picks to add players to a team that needs some talent.
Reid didn't exactly walk into a dynasty with the Eagles in 1999. The team went 3-13 in 1998 under Ray Rhodes and earned the second overall pick in the draft, which was used to take Donovan McNabb. The Eagles improved to 5-11 in Reid's first season, with McNabb starting the final six games and struggling. Then in 2000, the Eagles went 11-5 to kick off a string of five straight playoff berths under Reid and McNabb and five straight Pro Bowls for McNabb despite not having a 1,000 yard receiver until Terrell Owens in 2004.
I'm not saying that the Chiefs are going to turn into a dynasty. But Reid was a big part in turning around the Eagles franchise after Rhodes nearly killed it. The Chiefs have lost their way over the last decade, but if anyone can turn them around, it's Reid.
