ATLANTA — Tim Byerly wanted to make the most of his big chance to impress coach Paul Johnson. The junior quarterback rushed for 101 yards and passed for 69 to help the White team beat the Gold team 20-12 in Georgia Tech's spring game Friday night. But with conditions hampered by a 40-degree wind chill and heavy rain falling throughout the scrimmage, Byerly played a part in five of the game's 13 fumbles.
