FRAA/FRAR are pretty good as well, I like the attempt to actually translate into runs. UZR was good when available.
The last three years Clayton has been -10, -3, -6 in FRAA. WIth the minus 6 this year his is on pace to set his career worst(which the -10 is). Until 2004 he only had 2 season of a negative FRAA. A quite natural progession for an aging SS at a postion where few have ever it played it well past age 35.
