Sen'Derrick Marks playing at Pro Bowl level for Jaguars

The Jacksonville Jaguars signed Sen'Derrick Marks in the second wave of free agency last year and the move wasn't met with much excitement. Marks had a good season for the Jaguars his first year and in turn was rewarded with a five-year, $19.5 million deal with just $8 million guaranteed. So far in 2014, the Jaguars look as if they got a major bargain in Marks.

So far on the season, Marks is playing at a Pro Bowl level for the Jaguars. He has four sacks from the defensive tackle position, as well as double-digit hurries already in just eight games. He's already matched his sack total from last season and is on pace to crush his hurry numbers from that season as well.

If you want to look at advanced grades, they show even more so how well Marks is playing for the Jaguars. He's Pro Football Focus' 10th highest graded defensive tackle in the NFL and the third highest graded tackle in the AFC, behind Buffalo Bills tackles Marcell Dareus and Kevin Williams.

Some were worried that Marks' play might dip after he was no longer on a one-year "prove it" contract, but if you watch him on Sundays it looks like he's still playing like he's on a prove it contract.
