A few off the top of my head
Mark Seagraves - decent CB and was very steady, maybe got injured too much?
Paul Warhurst - played anywhere and was always good whether it was CB or midfield for us. Don't think he played upfront for us?
Simon Charlton - great LB who definitely flew under the radar
Mike Whitlow - good at either LB or CB
Scott Sellars - great left foot and was very solid for us, chipped in with a few goals as well
