Emmitt Thomas is the franchise leader in Interceptions (58, one more than Johnny Robinson) and was a two-time league leader in that statistic (1969 & 1974).  Making a case as the greatest Cornerback in Chiefs history, Thomas played thirteen of his NFL seasons with Kansas City and he was named to the AFL All-Star Team once (’68) and was a four-time Pro Bowl Selection (1971, 1972, 1974 & 1975), the last of which was First Team All-Pro worthy.  In that season his league-leading 12 Interceptions was matched by an also league-high 214 Interception Return Yards.  Like so many on the upper echelon of this list, Thomas was a member of the Super Bowl IV winning team and was also an AFL Champion in 1966.
