Chiefs general manager John Dorsey told the NFL Network's Albert Breer of the revelation Monday, according to Dan Hanzus of NFL.com. The Chiefs are also planning to wait until four days before the draft to make a final decision, and head coach Andy Reid will be involved in the selection process.
As one would expect, Dorsey did not reveal any of the four players to Breer.
However, the discovery that the Chiefs have narrowed their search allows us to also narrow our prognostications.
Here's an updated look at the five options the Chiefs are likely to be considering as the 2013 NFL draft nears, with percentage odds on each path included:
Texas A&M OT Luke Joeckel or Central Michigan OT Eric Fisher
An offensive tackle has always been high on Kansas City's draft board, even after Branden Albert was franchise-tagged for the one-year rate of $9.3 million in March. The subsequent release of right tackle Eric Winston made the idea even more likely.
Joeckel has been at or near the top of most draft boards dating back several months, and he's currently (as of April 2) being selected No. 1 by the Chiefs in nine of the 12 mock drafts at NFL.com. He's the consensus favorite to go No. 1 overall.
Fisher, who most still regard as the second-best tackle prospect, had an official visit with the Chiefs in late March, per Adam Schefter. While Kansas City was likely just doing their due diligence on every potential top pick, a good presentation from Fisher on that trip could have his name in the mix for No. 1.
A potentially elite offensive tackle like Joeckel seems to be the smartest bet, with Fisher another strong option should the Chiefs pass on Joeckel but still remain committed to fixing the offensive line.
Odds: 70 percent
West Virginia QB Geno Smith
A rather pricey trade to acquire former starter and No. 1 pick Alex Smith from the San Francisco 49ers and the signing of backup Chase Daniel once made it appear as if quarterback was off the Chiefs radar.
Their continued interest in Geno Smith might say otherwise.
According to Ian Rapoport of NFL Network, Smith is in Kansas City Monday and Tuesday for his official pre-draft visit.
While Kansas City simply wants to know everything they can about the draft's top quarterback, you can never count out any possibility when a team enters an offseason on the hunt for a franchise player at the game's most important position.
Still, Smith hearing his name called at No. 1 overall would be an undeniable curveball, barring a trade from Kansas City out of the top pick.
Odds: 5 percent
Florida DT Sharrif Floyd
Momentum appears to be building for Floyd to go No. 1 overall.
Greg Cosell, a respected film guru and executive producer for NFL films, said on NFL Network in early March (via Pro Football Talk) that Floyd is a player the Chiefs should consider with the top pick, "without question." Cosell went as far as to compare Floyd's potential NFL impact to that of J.J. Watt.
The draft history of both Dorsey and Reid also points towards a defensive player.
As Randy Covitz of The Kansas City Star points out, Dorsey helped select eight first-round defensive players in 12 drafts since 2001 with the Green Bay Packers, and Reid similarly picked eight defensive players in the first round during his reign in Philadelphia.
Floyd, a versatile and disruptive inside tackle, is likely on Kansas City's radar.
If combined with Dontari Poe, Tamba Hali and Justin Houston, Floyd could help create one of the game's best young defensive fronts in the NFL.
The odds are still against him being selected with the top pick, but Floyd shouldn't have to wait long for his name to be called in the first round. If the Chiefs don't take him, someone in the top five most certainly will.
Odds: 10 percent
Utah DT Star Lotulelei
Lotulelei's draft stock dropped like a ton of bricks when a heart ailment was discovered at the NFL Scouting Combine and forced him out of the workouts.
Since then, however, Lotulelei's heart and draft stock have both gotten healthier.
According to Adam Caplan of the Sideline View, five different heart tests and nine total all came back spotless for Lotulelei. The medical diagnosis? The former Utah star has been cleared to play professional football.
Considering Lotulelei was a rock-solid top-5 pick before the original scare, his draft stock should now return to pre-combine levels. If that's the case, Lotulelei should be right in the discussion for the No. 1 pick.
At his pro day last month, Lotulelei posted 38 reps at 225 pounds, ran in the low 5.1-second range in the 40-yard dash and finished swiftly in the shuttles. His overall workout looked much like Haloti Ngata's did coming out of Oregon.
A penetrating big man capable of playing both the 3- and 5-technique, Lotulelei brings instant impact to the next level.
While it would still be somewhat of a shock if an offensive tackle isn't the first pick, Lotulelei should be the next most likely option.
Odds: 15 percent
