Without reading through this entire thread, my answer is this:
Probably the best tandem, BUT:
1. without up-front pressure (which is a Chiefs' concern), no CB tandem could stop good opposing WRs forever.
2. The NFL has slanted the game more towards offense, and passing, in recent years. The concept of a true shut-down corner is more or less gone.
3. Law is excellent in run support as well. Dunno about Surtain. But it's fair to say that CBs have less impact on run defense than any other defensive position. So if your run defense still sucks...having great WRs won't save the day.
4. Older players have a few strikes against them. One is that they tend to get injured a bit more easily, and can take longer to recover. As Bill Belichick likes to say "depth in August is not the same as depth in November."
I'll keep my fingers crossed for their heatlh.
