Anyone who has watched Ken Hamlin should know he is a horrid tackler.
I don't think moving him to strong safety where he would need to be even more involved in the run game would be a good idea.
Patrick Watkins isn't a strong safety or a good tackler, either, but he at least seems to have improved versus what we witnessed last season.
Any offense that is able to commit to its ground game will likely give us trouble if their runners make it to the second level with any frequency.
