I've seen you say this for awhile but I gotta get my $0.02 in. The reason that Tejada has a higher value than a replacement player (correct me if I'm wrong, all these VORP and WARP stuff get confusing sometimes) is that there are fewer "ELITE" players at the shortstop position than there are at OF or LF.
SS: Tejada, Jeter, I'll put Furcal, and I'll give you Rent.
LF/OF: Manny, Vlad, Adruw Jones, Vernon Wells, Torri Hunter, Jacque Jones, Barry Bonds, Gary Sheffield, Lance Berkman, Carlos Beltran (I'll still put him in a high categroy, one bad year doesn't tarnish a career IMO), Miguel Cabrera, Bobby Abreu, Jim Edmonds, and quite a few more.
You may come back and tell me why I'm wrong but as of now, my list seems to show why those numbers (VORP, WARP) are ********.
