The Seahawks have signed former Purdue running back/fullback Brandon Cottom and former West Georgia linebacker Tyrell Adams. Both were tryout players for the three-day rookie mini-camp for Seattle. Offensive linemen Nate Isles and C.J. Davis were released.
Cottom only got eight touches in 2015 for Purdue (1 carry, 2 receptions, 1 two-point run, and 4 kickoff returns), but possesses the athletic traits at the position that the Seahawks love. At 6'2 and 262 pounds, he was the third-ranked SPARQ athlete at fullback per Zach Whitman's tracking, with a 4.62 40, a 4.33 short shuttle, 7.06 3-cone, and 33.5" vert.
He's a decent runner -- In his career he had 77 carries for 436 yards (5.66 YPC) and three scores, but adds some value as a receiver with 16 career receptions for 188 yards and three touchdowns. He has 33" arms and 10.75" hands - both on the upper spectrum for fullbacks.
My guess is that the Seahawks liked what Will Tukuafu and his pure size brought to the run game last year, but would potentially like a little bit more in the pass game out of their fullback. Tuk is reliable enough catching the ball, but is not dynamic once it's in his hands.
Does this look familiar?
Adams is a 6'2, 225 pound linebacker out of West Georgia (same school at Tory Slater) that led his team in tackles in 2014 and 2013. He's known to be a good coverage 'backer and finished last year with pass breakups and 10 passes defensed.
The Seahawks roster now stands at 90. I'd not be surprised if Seattle brings in more of these tryout players -- including Kasen Williams -- as the offseason goes on. The team tends to rotate players in and out at the back of their roster.
