I think he would DEFINITELY qualify for the 4th safety position. He got 94 tackles, 5 INTs, and 1 forced fumble last year.
Last year he signed a 2-year, $2.5 million deal with the Packers. So, he MIGHT be affordable. But, after this past season he might be slightly more expensive. Nonetheless, he's so so so much better than the backups we have now.
If George Wilson were to get injured, I would definitely have faith for Peprah to step in and provide solid play.
