Others had some answers and insights:

Tim Walton has mainly coached DBs. Has ties to some free agent safeties -- Kenny Phillips, Louis Delmas, LaRon Landry. #Rams

I honestly would not mind Tim Walton. & personally I am not that concerned with who the DC is. Make no mistake people, this is Fisher's D

The Lions will miss Tim Walton. I always wondered what he'd be able to do given more talent in the secondary.

I'm not taking that last tweet with a grain of salt. Fisher knows what he's doing and knows who he's hiring. Don't second-guess the Fish.

We'll learn more about Walton in the coming days, and especially as the season approaches.
