When the Chargers finish 6-10 in 2013, flip the calendar back to May 14th, and remember that as a date that will live in infamy for the franchise. Not only did we lose the great Chuck Muncie, but the Chargers suffered their first major injury of 2013 when Melvin Ingram tore his ACL during a non-contact OTA practice.
Yes, Ingram only recorded 1 sack in his rookie season, but there were signs of a major breakthrough coming in his sophomore campaign. A team-leading 29 quarterback hurries lets us know that Ingram was just a step away from being a pass-rushing force. One year of experience (anticipation, footwork, etc.) is sometimes all it takes for linebackers to get that extra step.
Now, the Chargers are left with a gaping hole on the outside edge, and very little salary cap room to address that need. The only returning players at OLB are now Jarret Johnson and (gulp) Larry English.
Can the Chargers overcome the loss of Ingram? Sure. But clearly, this isn't a roster that will be able to withstand much bad luck on the injury front. Absorbing a big hit on May 14th isn't a good way to start the year.
