The offseason additions that will make the most impact in 2019

NFL

As NFL teams look forward to their June minicamps, many will have some new faces on their rosters. There were plenty of offseason transactions, but not all of them will have the impact franchises desire. These are the roster additions that will generate the most impact in 2019.

Defense in K.C.

Something that lacked in Kansas City last season was a defense that could come up with stops when they were most needed. The Chiefs couldn't stop New England in the overtime in the AFC title game. The Chiefs finished 31st in total defense last season and head coach Andy Reid simply had enough. He fired defensive coordinator Bob Sutton and brought in veteran Steve Spagnuolo. Then, the Chiefs went to work on the roster.

Safety Tyrann Mathieu was brought in to be his All-Pro self. Spagnuolo can use Mathieu, who had 108 tackles and two interceptions last season in Houston, in a number of ways. He is an electric player than is a difference maker in the secondary.

The other notable addition to the Chiefs defense is DE Frank Clark. The 6-3, 265-pound Clark was acquired in a trade with Seattle. Clark brings an edge rush to Kansas City that Spagnuolo and the Chiefs defense desperately needs. Clark tallied 14 sacks last season in Seattle and if he can get to the quarterback like that in K.C. the Chiefs defense will be much improved.

Jets Ready for Takeoff

The signing of All-Pro RB Le'Veon Bell instantly upgraded the New York Jets offense. Second-year quarterback Sam Darnold now has a legitimate running threat that will take some of the pressure off of him. Bell did not play all of last season sitting out over contract issues, but he is the type of player that can take over games. In five seasons, Bell have over 8,000 all-purpose yards. He is dangerous as a runner and as a receiver. He is not the only big pickup for the Jets either.

Linebacker C.J. Mosley is an every-down player that will make an impact on the Jets defense. The Jets finished 25th in total defense and 29th in scoring defense last season. Mosley averaged over 100 tackles a season playing in Baltimore the past five years. He joins a contingent of young prospects - including first-round pick DT Quinnen Williams - that could make the Jets a top-10 defense.

OBJ to Cleveland

The Browns offense did some very good things in 2018. Quarterback Baker Mayfield is emerging as a star. He will continue to emerge now that he has a legitimate vertical threat at wide receiver. Beckham ranked sixth in vertical yards per game over the past two seasons. He should thrive, as should Mayfield, in the Browns offense.
