In what capacity? Overall? It depends on what you're looking for in your safeties. There are at least 30 safeties--probably more--in the NFL right now that I would take over him, though.
To get into my top 20, he'd have to get a lot better in coverage, which, granted, he might. Speed will never be a strength of his, but that doesn't preclude him from being effective against the pass.
At least 30, and probably more? Wow, your opinion of him is basically that he sucks huh?
Here is a list of all Safeties who started 8 games last year. I highlighted the ones that I think are at least a debatable comparison to Chung, and bolded comment where appropriate
I tried to be exceedingly generous in considering anyone even in the ballpark as potentially comparable.
I came up with 22 players that deserve even a mention, and many of them clearly are not as good as Chung.
Who are your 'at least 30, maybe more'.
