NFL free agency has begun, and a slew of former SEC players are set to cash in this season.

Malik Jackson (Tennessee) and Mark Barron (Alabama) are the biggest offseason winners thus far, but that could change.

Three such players have already been assigned the franchise tag by their current employers, meaning that Von Miller (Texas A&M), Eric Berry (Tennessee) and Alshon Jeffery (South Carolina) will again suit up for their respective teams in the Denver Broncos, Kansas City Chiefs and Chicago Bears this fall. All three figure to command top money in 2017.

They are among a slew of former SEC stars whose talents will be leading to big paydays in the upcoming days and weeks ahead as the NFL free agency period plays out.

Last offseason, Jeremy Maclin (Missouri) signed a five-year, $55 million deal with Kansas City. Chris Culliver (South Carolina) signed a four-year, $32 million deal with Washington.

Here’s a look at some of the best about to see the big NFL money this offseason.

DT Malik Jackson (Tennessee)

Jackson recovered a fumble for a touchdown to help the Denver Broncos win Super Bowl 50.

A fifth-round pick out of Tennessee in 2012, he signed a six-year, $90 million deal to help anchor the Jacksonville Jaguars’ defensive line.

OLB Mark Barron (Alabama)

The former Crimson Tide star never made much of an impact at strong safety, but has begun doing just that since converting to linebacker for the Los Angeles Rams.

Barron signed a five-year deal worth a reported $45 million after converting to linebacker last season and responding with a team-best 116 tackles and three forced fumbles.

OLB Von Miller (Texas A&M)

Miller left Texas A&M before the Aggies joined the SEC, but the Super Bowl MVP for the Denver Broncos has been a devastating force since entering the league in 2011. He finished in the top 10 in sacks and posted double-digit sacks in four of his five campaigns, including a solid 2015 regular season that featured 11 sacks.

His dominant performances in the AFC Championship Game in the Super Bowl couldn’t have come at a better time. The Broncos have until July 15 to get a deal signed, or Miller will play the 2016 season on the franchise tag, which is set at $14.13 million for linebackers.

S Eric Berry (Tennessee)

The Kansas City Chiefs’ 2010 first-round pick capped a remarkable rally from cancer by being named the Associated Press Comeback Player of the Year. Diagnosed with Hodgkin’s lymphoma in November 2014, Berry endured chemotherapy treatments before coming back this season to record two interceptions and finish third on the team in tackles to reach his fourth Pro Bowl in his six NFL seasons.

The franchise tag label means that Berry will make an estimated $10.6 million this year slated for safeties.

WR Alshon Jeffery (South Carolina)

The former Gamecocks star has proven himself extremely productive when healthy for a Chicago Bears offense that lacks playmakers. He appeared in just nine games in 2015, but matched a franchise record with three consecutive 100-yard receiving games against Detroit, Minnesota and San Diego.

Jeffery boasts 12 career 100-yard receiving games in his four seasons, tying him for fifth in team annals. Chicago has until July 15 to work out a long-tem deal with him.

Under the non-exclusive tag worth $14,599,000 the Bears opted to use, Jeffery is allowed to negotiate with other teams, and the Bears have the right to match any offer. If he signs with a different team, that team will owe the Bears two first-round draft picks in compensation.

C Ben Jones (Georgia)

The versatile former Dawgs star signed a four-year contract worth a reported $17.5 million with the Tennessee Titans, including $7.5 million in guaranteed money, according to published reports. Jones had played with the Houston Texans since being drafted in the fourth round out of Georgia in 2012. His ability to play either guard or center comes in handy when injuries force to shuffle their lineups up front. Jones will be a welcome addition to a Tennessee offensive line that struggled in 2015.

FS Reggie Nelson (Florida)

The former Gators star is coming off a Pro Bowl season with the Cincinnati Bengals in which he shared the NFL lead with his eight interceptions.

Nelson, who will be 33 in September, could re-sign with the team after enjoying one of his most productive seasons of his career. The Bengals may choose to go with youth, but the Washington Redskins could be among the other teams interested in Nelson’s services.

Spotrac.com is projecting his market value at 4 years, $19.4 million.
