A pair of players who have seen plenty of criticism from Kansas City Chiefs fans are receiving some praise from the stats-based site Pro Football Focus. Most of you saw this already but Pro Football Focus called Chiefs defensive ends Glenn Dorsey and Tyson Jackson the Chiefs "Secret Superstars".

The Chiefs completed their defensive line with a third first round pick in this year's draft in the shape of Dontari Poe from Memphis. If they have managed to identify another player of similar run-stuffing ability, their D is well on its way to being an extremely formidable unit. Though neither Glenn Dorsey nor Tyson Jackson will ever be redeemed in the eyes of some people who care only about the sack stats, they have developed into two of the best run-stuffing defensive linemen in the NFL. That is why they are Kansas City's Secret Superstars.

After this season is when things will get interesting with both of those players. Dorsey is entering the final year of his contract and Jackson, who has already restructured his contract once, is due a very large amount of money next season, the final year of his rookie contract.

The Chiefs have consistently pointed out that defensive ends in their defense aren't designed to put up big sack numbers so if that's true then they may not be as concerned that there isn't a major impact there.

Do you extend both players? Extend just one of them? Hope in-house players develop? This is another one of those story lines that we'll be following all season.
