In a very ass backwards way, this is a blessing. Hold on, let me rationalize. I don't harbor any ill will towards a player like Hau'oli Kikaha who has a history of knee problems. In fact, I was looking forward to seeing what he could bring to the table this year because he had an extremely promising rookie campaign. I hope he heals up and comes back better than ever, because - in time - I think he can be a pretty productive situational linebacker.
Unfortunately, someone had to get catastrophically injured to curve the undying optimism that I have about the Saints defense every June, and this year that player just happened to be Kikaha. It sucks that one of the few reliable pass rushers on the roster is already looking forward to 2017, but at least this gives me plenty of time to accept that the Saints stand next to no chance of getting to the quarterback this upcoming season. At least I won't be expecting a bunch of sacks and quarterback hurries like I would trick myself into doing had the front seven had started the year fully healthy.
Technically my expectations should have already been low considering the fact that opposing QB's basically had enough time in the pocket to shit, shave, and shower before worrying about any oncoming defenders last year. However, there's something about not watching your team play for 6 months that programs you to believe that they have spent every single day of those 6 months getting exponentially better at the things they sucked at. That's why I pretty much needed Kikaha's torn ACL to bring me back to reality during OTA's, because had we gone any further without disappointment then it just would have hurt that much more when I came crashing down to earth.
P.S. Seriously though, get well kid.
