For the Kansas City Chiefs, the foundation of building a championship football team is to do it through the draft. That's been the motto of general manager John Dorsey since he arrived in Kansas City two years ago.
But that doesn't mean the Chiefs won't use free agency as a way to build their roster.
They have done that and will continue to do so to not only add players to a team that just had back-to-back winning seasons for the second time in two decades, but to help replenish a roster that has players who will hit free agency themselves.
The NFL's new league year won't begin until March 10. That's the first date that players who are free agents can sign with another team.
The only exception is players who weren't under contract at the end of the past season, and those players can be signed to reserve or futures contracts, in which the Chiefs have signed 19 players so far this offseason.
For players who are set to become unrestricted free agents across the NFL, there are a few marquee players who will be making headlines as we get closer to the start of the new league year.

WR Randall Cobb
While things can change, the number of standout receivers currently scheduled to become available in free agency this offseason is staggering.
You're talking players like the Dallas Cowboys' Dez Bryant, the Denver Broncos' Demaryius Thomas, the Philadelphia Eagles' Jeremy Maclin, the San Francisco 49ers' Michael Crabtree, the Green Bay Packers' Randall Cobb and the Baltimore Ravens' Torrey Smith.
Of that group, four finished in the top 11 in the NFL in receiving last season (Thomas, Bryant, Maclin, Cobb).
Cobb finished the 2014 season for the Packers with career highs in receptions (91), targets (126), yards (1,287) and touchdowns (12). His 618 yards after the catch ranked fourth in the NFL among receivers.
Maclin also had a career year for the Eagles with 85 receptions for 1,318 yards and 10 touchdowns, also excelling in yards after the catch, ranking seventh with 522.
In 2014, the Chiefs finished No. 15 in the NFL in yards after the catch with 2,021.

It's hard to believe that at least a few of these receivers won't re-sign with their own teams, but as we stand right now, the group looks to be pretty impressive.
Along the defensive line, there are a few names you will continue to hear much about as we move through the offseason.
According to NFL.com, the Detroit Lions' Ndamukong Suh is one of the top free agent defensive linemen available, along with the New York Giants' Jason Pierre-Paul. The Chiefs' Justin Houston is also listed as one of their top 10 free agents scheduled to hit the market.
Suh has missed just two regular season games in his five-year career thus far and finished the 2014 campaign with 53 tackles and 8.5 sacks.
Along the offensive line, the 49ers' Mike Iupati, the Broncos' Orlando Franklin and the Cincinnati Bengals' Clint Boling are a few names that should get some attention as well.
Each of those players finished the season in the top 20 of Pro Football Focus’ grading scale for guards (Franklin – 13, Iupati – 14, Boling – 19).
Another offensive lineman scheduled to hit free agency is former Packers' first-round pick and starting right tackle, Bryan Bulaga, who ranked fourth in the NFL according to PFF.
The Chiefs have three starting offensive linemen that are scheduled to become free agents on March 10—center Rodney Hudson, left guard Mike McGlynn and right tackle Ryan Harris, as well as backup Jeff Linkenbach, who is also scheduled to hit free agency.
The Chiefs have a lot of decisions to make with not only their own free agents, but also whom they might want to target if any of these other guys do become available when the free agency period begins.
In any case, we'll have you covered at KCChiefs.com with anything official that happens as Dorsey and company builds towards 2015.
