Jeff Steele could only tip his hat to a performance unlike anything the Johnson boys basketball coach had ever seen — one good enough to end the previously unbeaten Knights’ historic season. Top-ranked Jonesboro closed out a shut-down defensive effort by holding Johnson to a lone fourth-quarter point until the final 52 seconds of play in the Class AAAA state quarterfinals. The defending state champion Cardinals outscored the fifth-ranked Knights 13-1 during that span of 7:08 in the final period and advanced to the state semifinals with a 50-35 win over Johnson on Thursday in Oakwood.
