They need to acquire a LG, DT, ILB and add more depth in various areas of the roster.
It's imperative that the Chiefs can put together a solid '12 draft class in order to continue to move this franchise in the right direction in the future.
That being said, here are my best-case scenarios for every Chiefs pick in the 2012 NFL draft.
To me, this pick is a win-win for the Chiefs in the first round.
With DeCastro, KC would likely have a franchise left guard who has enough upside to garner multiple Pro Bowl selections in his NFL career.
He would instantly make everyone look better on KC's offensive line and would help to open up much bigger holes for Jamaal Charles and the running game.
With each passing day, the former Stanford guard is looking more and more like the best possible option for Kansas City in the first round of this draft.
It's been well documented that the Chiefs were planning on adding more competition at QB this offseason.
So far, they have just signed free agent Brady Quinn.
Landing the 6'7" gun-slinging QB Brock Osweiler would be a bold statement by the Chiefs brass, if he is still there when the team makes their second selection of the draft.
He has all the tools to become a solid QB in this league, and he could be a huge steal.
Although he is not likely to beat out Matt Cassel for the starting job in 2012, KC could eventually solve some of their problems at QB if they can get Osweiler on the draft's second day.
For the past few seasons, defensive tackle has been a major position of need for the Chiefs.
Since the Chiefs have done nothing to address it in free agency thus far, they need to find a DT in the draft that has the potential to come right in and start immediately.
Washington's Alameda Ta'amu fits this profile perfectly, and he could still be on the board when KC makes their third-round selection.
His 6'4", 348-pound frame and run-stopping ability at nose tackle makes him an ideal candidate for Kansas City.
With just two legitimate pass-rushing threats on their current roster, the Chiefs desperately need to address DE.
There will likely be several possibilities for pass-rushers in the middle rounds, but taking former Cincinnati defensive end Derek Wolfe in the fourth round would be the best scenario for the Chiefs.
The former All-Big East First Team selection has a nonstop motor and draws comparisons to ex-Chief and Pro Bowl DE Jared Allen.
He notched 16 total sacks over his last two seasons and could give KC the pass-rushing threat from the edge that they were missing last season.
Former NC State Wolfpack linebacker Audie Cole has been slowly rising his way up the draft boards in recent weeks.
The Chiefs would be fortunate if they could get him with the 11th pick in Round 5, considering how good of a player he could become at the next level.
Cole is as versatile as they come at ILB, as he is decent in pass coverage and excels in covering sideline to sideline on defense.
If Kansas City is able to land Cole, he would be the final piece of a linebacking corps that already has a good shot at being one of the best units in the league next season.
When teams start getting into this portion of the draft, depth becomes a major point of emphasis.
That's why CB prospect Mike Harris would be a good fit for the Chiefs in the sixth round.
He is very good in man coverage, which is something that KC head coach Romeo Crennel is looking for in his cornerbacks.
Plus, you can never have enough DBs with the way that the passing game has evolved in today's NFL.
Even though the Chiefs already added free-agent TE Kevin Boss earlier this offseason, it wouldn't hurt to draft one later this month.
James Hanna would be an excellent option in the seventh round, considering that he will be one of the most talented prospects on the board if he's still available for this Chiefs pick.
He's a solid receiving tight end and would have a good shot at becoming KC's third-string TE in 2012.
Ex-Penn State wideout Derek Moye would be an absolute steal this late in the draft.
The Rochester, PA native racked up nearly 2,400 receiving yards and 18 touchdowns in his PSU career.
Even though he is currently projected to be undrafted, there's little doubt in my mind that Moye could easily go in the sixth or seventh round, considering how many teams still need WR depth.
At 6'4", Moye could give KC another vertical threat in their passing game, which would effectively open up the field even more for Matt Cassel and the offense.
After all, what more could you ask for out of a late seventh-round pick?
