\u00a9 Mark J. Rebilas-USA TODAY Sports<img src="https:\/\/raiderssnakepit.redescribe.com\/wp-content\/uploads\/sites\/2\/2018\/06\/USATSI_10499069_168380803_lowres.jpg" class="wp-image-1880 aligncenter size-full" alt="">\n\nIt\u2019s been a busy afternoon for the Raiders on the transaction wire. An hour after adding nose tackle Ahtyba Rubin, Oakland reportedly has agreed to terms with defensive end Frostee Rucker. Both Rubin and Rucker are expected to be on the field Tuesday for the team\u2019s mandatory minicamp:\n\nLet\u2019s take a look at Rucker.\n\n<strong>Who is he:<\/strong> He is entering his 13th <sup>th<\/sup> season. He spent six seasons with the Cincinnati Bengals, one season with the Cleveland Browns and the past five seasons with the Arizona Cardinals. Rucker was fully healthy last season for the first time in three years. He started all 16 games for the Cardinals. He had just 29 tackles and 1.5 sacks. Rucker isn\u2019t much of a pass rusher. He has just 21.5 career sacks.\n\n<strong>30 club member:<\/strong> Rucker will be 35 in September. Rubin will be in 32 next month. The Raiders haven\u2019t gotten any younger this offseason.\n\n<strong>Raiders\u2019 connection: \u00a0<\/strong>New Oakland defensive coordinator Paul Guenther was on the Bengals\u2019 coaching staff during Rucker\u2019s six seasons with the team. Rucker joins Reggie Nelson, Leon Hall and Emmanuel Lamur as defensive players in Oakland who have played under Guenther.\n\n<strong>Why they signed him:<\/strong> Depth. They are not expecting Khalil Mack to be at the minicamp because of his contract issue. The holdout could extend into training camp. So, Rucker is good insurance.\n\n<strong>What to expect:<\/strong> Even though, he started last season, I don't think Rucker is a sure thing to make the team.\u00a0 He has a backup competition with Tank Carradine and Fadol Brown.
