Patriots defensive tackle Alan Branch will face his former team Feb. 1. (NFL Game Rewind)

Much is shared between the New England Patriots and Seattle Seahawks.

And as the two teams prepare to face one another in Super Bowl XLIX at University of Phoenix Stadium, several of whom are preparing to face former teammates and colleagues.

Here is a look into 12 of the personnel ties that bond the conference championship winners heading into the Feb. 1 kickoff.

Landon Cohen, Defensive Tackle: Cohen has been a member of nine different NFL teams since entering the league as a seventh-round pick by way of Ohio in 2008. And During both the 2010 and 2011 seasons, the 6-foot-1, 300-pound defensive tackle was a member of the Patriots. Cohen played in three regular-season games and started one for New England over that span, registering four tackles.

Kevin Pierre-Louis, Linebacker: A Norwalk, Conn., native and a Boston College graduate, Pierre-Louis played in 44 games for the Eagles before being selected by Seattle in the fourth round of the 2014 draft. The 6-foot-1, 232-pound linebacker went on to play in seven games and register 10 tackles as a rookie this season. He was placed on injured reserve with a shoulder injury in November.

Steven Hauschka, Kicker: Hauschka grew up in Needham, Mass., where he played soccer and lacrosse before attending Middlebury College in Vermont. He was cut Panthers’ varsity soccer team in 2003 and went on to serve as both kicker and punter for the football team over his next three years. Haushka enrolled as a graduate student at N.C. State and finished 16-of-18 on field goal attemps for the Wolfpack football team. The 2008 undrafted free agent has been part of seven professional teams since, including the now-curtailed Las Vegas Locomotives of the United Football League. The 29-year-old has been with Seattle since 2011.

Jesse Williams, Defensive Tackle: Williams played 13 games in front of Patriots linebacker Dont’a Hightower while at Alabama in 2011.  Hightower proceeded to be drafted by New England in the first round that following April, and Williams proceeded to be drafted by Seattle in the fifth round the April after. The 24-year-old Australian defensive tackle was placed on injured reserve in August after suffering a second knee injury. He is also teammates with former Crimson Tide offensive lineman James Carpenter.

Alvin Bailey, Offensive Tackle: Bailey was a sophomore guard at the University of Arkansas when Jake Bequette was a senior defensive end. And one year after Bequette departed for the NFL and became a Patriots third-round pick, Bailey forwent his final season of eligibility and went undrafted before signing with the Seahawks. The 6-foot-3, 320-pound Bailey has played in 28 games for Seattle since then, starting five, while the 6-foot-5, 265-pound Bequette has played in eight and has now become part of New England’s practice squad.

Cliff Avril, Defensive End: The Seahawks’ Avril and the Patriots’ Rob Ninkovich manned the Purdue edges back in 2005, playing in 10 games together. Ninkovich went on to be drafted by the New Orleans Saints in the fifth round that spring, and Avril went on to be drafted by the Detroit Lions in the third round two years later. The two Boilermakers have combined for 13 sacks in 2014 and 88 in their NFL careers.

Russell Wilson, Quarterback: Wilson transferred from N.C. State to Wisconsin in 2011, where he crossed paths with another future fourth-round pick in Patriots halfback James White. Wilson handed off or passed to White nearly 160 times that season. A total of 713 rushing yards, 150 receiving yards and six touchdowns were the byproduct.

Brandon Browner, Cornerback: Before the 6-foot-4, 221-pound Browner lined up at corner for the Patriots this season, he lined up there for the Seahawks over the previous three seasons. Browner started all 36 games for Seattle during his time there, and he was voted to the Pro Bowl 2011 after picking off six passes for 220 yards and two touchdowns.

Alan Branch, Defensive Tackle: Branch was part of the Seattle defensive front that went against the Patriots back in 2012, and the 6-foot-6, 325-pound defensive lineman remained a part of it for a total of 31 games in all. And after spending the 2013 campaign with the Buffalo Bills, Branch has spent the second half of the 2014 campaign with the Patriots. He played in the final eight games of the regular season, notching 13 tackles and a batted pass.

Sealver Siliga, Defensive Tackle: Before Siliga earned a starting spot next to Vince Wilfork on New England’s defensive line, he was looking to earn a roster spot on his third team since going undrafted out of Utah in 2011. And after stints with the San Francisco 49ers and Denver Broncos, that third team happened to be the Seahawks. Siliga was traded from San Francisco to Seattle in August of 2013, and the 6-foot-2, 325-pound Ute was later released midway through September before spending time on the team’s practice squad. He joined New England’s practice squad that October and has since played in 12 regular-season games for the Patriots, starting nine, to record 55 tackles, 5.5 sacks and a forced fumble.

Carl Smith, Quarterbacks Coach: Smith served as a Patriots assistant head coach and quarterbacks coach in 1997, before serving as tight ends coach for the 1998 and 1999 seasons. He became Seattle’s quarterbacks coach in 2011.

Pete Carroll, Head Coach: Seattle’s Super Bowl-winning head coach once held the same title with New England. From 1997 through 1999, Carroll went 10-6, 9-7 and 8-8, before being replaced by Bill Belichick in 2000. Carroll and Belichick are the lone head coaches owner Robert Kraft has hired in his 21-year Patriots tenure.
