I've been actually wondering since a few wks back when Tre initially came off the IR if they would consider moving Tre back to safety, paired with Poyer (who was "healthy" at the time). This would give him ability to move around the field more "freely", vs CB where there's a lot of cutting/unknown movements. I know they were testing it White's rookie season, but obviously kept him at CB.
Wonder what they'll do back there and with Tre but it's interesting to consider.
