As coaches and general managers prepare to make potentially franchise-altering decisions in the 2015 , now is the perfect time to look back and see how the choices made last year played out on the field. Bucky Brooks is reviewing and grading each team's rookie cla s from 2014, as well as highlighting what organizations should hone in on at this month's NFL -- continuing with the AFC West below. Denver Broncos After heavily dipping into the free-agent pool to land veterans , , and , John Elway had the in "ready to win" mode even before the 2014 took place. Thus, the team didn't hold high expectations for the relatively small 2014 rookie cla s heading into the regular season. made the biggest contribution of anyone in the group, playing in all 16 games -- mostly as the nickel corner in Denver's sub-packages -- and logging two starts. He displayed solid cover skills on the perimeter and impre sed coaches with his improved toughne s and physicality. Although a pair of ers ( Jr. and Talib) likely will keep Roby at CB3 next season, he certainly has the tools to be a quality starter down the road. couldn't crack the receiver rotation as a rookie, but the big-bodied pa s catcher should be a key contributor in his second season. Grade: C Combine focus: The will investigate the top offensive tackles in the 2015 draft cla s to determine if there is an Alex Cobb Jersey ultra-athletic edge blocker ideally suited for new coach Gary Kubiak's zone-based scheme. The emphasis on athleticism should put Pittsburgh's , Stanford's and Texas A&M's under the microscope. The potential departure of will prompt Elway and his colleagues to study the tight end group for another athletic pa s catcher to add to the mix. Miami's could be the focal point of the ' attention after his solid performance at the . Kansas City Chiefs The didn't get immediate returns from top pick , but the pa s rusher was selected as an insurance policy for the po sible departure of (and/or potential cap casualty ) following the 2014 season. Although the rookie pa s rusher didn't crack the rotation, he is poised to make an impact when called upon. gave the a dynamic multipurpose weapon on offense and provided a few explosive plays in the return game. Defensive back earned significant snaps down the stretch; he should be in the mix for a prime role as a second-year pro. Lastly, John Dorsey and Andy Reid also plucked a starting kicker from the undrafted free agent market ( ). Grade: C+ Combine focus: The desperately need a standout receiver to take their offense to the next level. With failing to post big numbers as the WR1 in Reid's offense, Kansas City could take extended looks at Louisville's , West Virginia's , Michigan's and Mi souri/Oklahoma product . The team also could look to add some complementary playmakers on the outside, po sibly leading to extensive conversations with Auburn's , USC's and Arizona State's . Oakland Raiders Despite a disappointing record, the ' front office deserves a pat on the back for nailing it with the 2014 rookie cla s. Linebacker is a future er with a rugged game and a knack for playmaking off the edge. stepped in and performed admirably as the team's starting quarterback. He sparked the offense with his athleticism and gunslinger's mentality, while also displaying leadership and poise beyond his years. The received solid contributions from OL , DT and DB -- a huge bonus, considering their respective draft slots. Given the overall impact delivered by Oakland's first-year players, it appears the foundation is in place to help the team emerge as an eventual playoff contender under Jack Del Rio. Grade: A Combine focus: The must upgrade the speed, athleticism and playmaking on the perimeter for Carr to develop into the franchise quarterback that team officials envision. Oakland lacks a proven WR1 -- snagging one in the 2015 draft must be a top priority. Alabama's and West Virginia's certainly will receive a lot of attention, but expect the team to take hard looks at USC's , Ohio State's and Miami's as po sible targets on Day 2. The also will spend time studying pa s rushers like Mi souri's and Nebraska's , as the team could stand to upgrade the defensive front. San Diego Chargers The didn't have a bunch of pre sing needs entering last year's draft, but they added one of the top cover corners in the 2014 cla s in . Although he logged just six games due to injury, Verrett flashed tremendous talent, savvy and instincts during his limited action. When he returns to the field in 2015, Verrett should be an impact player on the ' defense. Linebacker and defensive tackle didn't contribute much as rookies and will need to show substantial development during the offseason to become key role players next season. Running back was definitely a nice find as an undrafted free agent. Grade: C Combine on NFL Network In advance of the draft, Marcus Mariota and others will look to showcase their skills at the combine (Feb. 17-23), only on NFL Network. Combine focus: The have a number of free agents set to hit the open market. Thus, the team will have its hands full at the NFL attempting to identify po sible replacements. From investigating a number of offensive tackles (guys like Stanford's , Miami's and Pittsburgh's ) to scouring an intriguing running back cla s (Indiana's , Miami's , Alabama's and Boise State's come to mind), the have a lot of work to do in Indianapolis to keep the team in contention in the AFC West.
