Sometimes, too much of a good thing can be a bad thing. So it is with Tennessee's defensive line.
Tennessee has a very, very deep defensive line with lots of talented players at each position. What they don't have is four clear cut starters.
At defensive end, Derrick Morgan looks like he'll be the only absolutely stable player for the next few years.
Jason Jones could be a Pro Bowl player, but he's constantly injured. The same thing goes to a lesser extent with Dave Ball.
Jacob Ford is a reliable backup, but that's all he is. Karl Klug has talent, but doesn't look like anything special. Even undrafted free agent Pannel Egboh from Stanford looks like he could contribute, but none of them are good enough to start across from Morgan on every snap.
Defensive tackle is worse. There's Shaun Smith, who is a talented veteran, but obviously not a long term solution. Jurrell Casey is impressive, and he might be the other default starter, but he's just a rookie.
After those two, there's Jovan Haye, Sen'Derrick Marks and Malcolm Sheppard, who are all serviceable players, but not starters.
Then there's Zach Clayton, who appears to be on his way to the roster, but he was just a seventh rounder, and won't be a starter either.
The Titans have 15 players on the roster that play defensive line. That's simply too many. Someone needs to separate themselves from the rest of the pack and become a clear cut starter before the Titans will be back to playoff contention.
Just a few years ago, the Titans had one of the fiercest defensive lines in the NFL. They need that back if they want to win now, win later and win big.
