You don't say why two disks were kicked or when it happend so sdc may be out-of-whack a bit.  Sounds like sdc got kicked first.
So...I would do a bad-block scan on sdb2 so it can remap the bad section and re-build as you've been trying to do.

If you REALLY want to use sda and sdc just rebuild the array with --create and leave sdb out of it.  You shouldn't lose much data if
sdc is current.

Better still, do that --assemble and leave sdb out of it.
i.e.

 mdadm --assemble --force /dev/md1 /dev/sda2 /dev/sdc2

Then it will have to use a2 and c2.
