I don't get why jimmies get rustled over this every time. Chavis was a great Defensive Coordinator, but he wasn't without his flaws.

No doubt he will improve tamu's defense--kinda like LSU's offense logically has to improve this year (I mean, its virtually impossible for it to get worse

). But Chavis also had rosters loaded with NFL talent:
Lamin Barrow, Ego Ferguson, Lavar Edwards, Tharold Simon, Sam Montgomery, Tyrann Mathieu, Bennie Logan, Kevin Minter, Eric Reid, Barkevious Mingo, Ron Brooks, Brandon Taylor, Michael Brockers, Mo Claiborne, Pep Livingson, Drake Nevis, Kelvin Sheppard, Patrick Peterson, Al Woods, Perry Riley, and Chad Jones were all players under Chavis. All were drafted. In this upcoming draft, Jalen Collins (CB) will likely be a first round pick despite only getting a start 7/13 games.

Craig Loston, Freak Johnson, Ryan Baker, Rahim Alem, Danny McCray, Chuck Alexander, Chris Hawkins, and Harry Coleman (Beast) were all picked up as free agents as well.

For comparison's sake, tamu has a total of 9 defensive players total in the NFL overall. This isn't to say Sumlin has not/will not bring the defensive talent level up (he'll have to, since Chief doesn't recruit), but the sheer volume of defensive talent won't be the same at tamu.

He's a great coach and will bring tamu's defensive performance up. But as the article stated, there won't be (and they don't need) elite level defenses up in College Station; marginal improvement will be enough--kinda like LSU QB play only needs to be marginal.
