"Not good" is an understatement. I would suspect that the weight loss is as much, if not more, in response to the bulging disc as for "quickness." Furthermore, "beer gut" defensive linemen tend to have poorly developed abs, which is a major support factor for the back.
Two questions come to mind right off the bat. First, will it recur? Recurrence is not uncommon following appropriate treatment, especially following a triggering of back spasms which the typical trauma a lineman sustains can easily initiate. That's not to mention compromises required at the weight room to avoid aggravation. Second, will his new lower weight, which he enjoyed in his college success, allow him to compete at the NFL level with equivalent results.
That single bit of information about the bulging disc just killed my remaining optimism for Okoye. I love the guy, but I think it's the beginning of the end. I'm looking in my crystal ball and I see his career ending within two years. Here's why, off the top of my head:
1) It is definitely limiting his weight training, and will continue to do so. No one can or should be giving 100% exertion on squats --the most important routine at his position-- with a bulging disc.
2)He's only 23 and he has this injury.
3) Bulging discs don't remedy themselves without surgery. That means it's going to have to be managed. That means less reps, less exertion, dwindling numbers, and a less valuable DT on this team. Okoye's in no position to sustain that at this point.
4) If it isn't managed or operated on, he's due for spasms, nerve damage, and things much more painful, which I don't want to think about.
I hope I'm wrong about this, but it's what seems probable. I want to think that it can be managed, he'll be faster, he's putting it all together, and things will pan out... But just try saying the term "bulging disc" without wincing, or visualizing hampered performance.
My crystal ball also tells me that Earl Mitchell is our three technique DT of the future. When I look to see what our solution at nose will be, it gets murky (Don't buy your crystal balls at Wal-Mart).

Here's an article about John David Booty getting surgery for the same injury. I remember seeing a report about him doing a lot of core ab training as part of his rehab. Keep in mind that QB's don't have to do leg exercises like linemen in order to compete.
