Editor's note: Auburn has a rich history of sending players to the NFL. With that in mind, beat writer Ryan Black takes a look at each former Tiger that finds himself on an NFL roster (or should be once free agency and training camps shake out). The series will begin with those who have already been in the league for more than one season and conclude with the latest crop of players to land in the NFL, either through the draft or as an undrafted free agent.
Sen'Derrick Marks, Jacksonville Jaguars
Position: Defensive tackle
Drafted: Taken in the second round (No. 62 overall) by the Tennessee Titans in 2009
Career stats (through five seasons): Appeared in 67 regular season games (42 starts); 133 tackles, seven sacks; five forced fumbles; three fumble recoveries2014 outlook: Talk about a return on investment. After spending his first four years in Tennessee, Marks signed a one-year deal for $1.5 million (including a $920,000 signing bonus) with AFC South rival Jacksonville last April. Before the season even ended, the Jaguars tore up the contract and gave Marks a new one, good for four years and $22 million. And why not? He set career-highs in sacks (four), passes defensed (eight), forced fumbles (two) and fumble recoveries (three) while starting all 16 games. And Jacksonville thinks he can be even more effective this year by taking a "less is more" approach. Marks was on the field for 83 percent of the Jaguars' defensive downs last year. If that percentage drops, expect his individual numbers to be even better in 2014.
