The statistical trends aren't promising.
Firstly, RommelDAK's research from two seasons ago strongly suggests that, barring a clear reason to expect otherwise, players that are underperforming at the W4/5 mark aren't likely to rebound. Ryans isn't immune from consideration there.
Second, there are some disturbing trends in his rate stats:

Some of it may be attributable to the decline in tackle opportunity and nagging injuries that have limited his range at times, but the decrease in his percentage of team solos is evidence of the added competition for tackles that many have noted in the thread.
However, there are some reasons to remain optimistic:
1. Ryans is still talented.
He's been on a number of stretches (usually when healthy) over the past two seasons where he's been on strong runs regardless of the opportunity issues and competition issues noted above. In particular, Ryans was on pace for nearly 120 solos through eight games in 2007 and started 2008 on a 100 solo tackle pace as well. I also think he's still passing the eyeball test on most snaps.
2. The Texan tackle opportunity and snap count numbers this year don't jive.
Snap count is where it was during the poorer Texan defensive seasons, yet the tackle opportunity is worse than ever. In fact, his last two weeks of opportunity have been brutal -- 36 against Oakland and 43 against Arizona (a game with 16 rush attempts against, fewer than the worst average in the league though five weeks) -- and he's had only one game with more than average opportunity (W1 vs TEN). There's a very reasonable argument that the tackle opportunity number is more likely to move in Ryans' favor than the snap count number. Whether he takes advantage is another issue of course.
3. Ryans' peripheral stats are reassuring.
His assisted tackle numbers project to equal those of his first three seasons. He has four TFLs and two quarterback hits. He has a FF/FR and a single PD. Those numbers suggest he's still around the ball. His primary competition for tackles -- Brian Cushing -- isn't out-tackling him (they're even at 22 solos though Cushing has six more assists).
It seems clear that Ryans can no longer be considered a clear top five linebacker and potentially not even a LB1. However, it'll be shocking if his current solo tackle pace (just 70) persists all year. Expect his numbers to pick up over the next few weeks.
