Morrowman could not have reacted fast enough, because once the screw made it through the tire that unless he could stop on a hairs width as soon as the screw punctured the tire outer tread, that screw was going to do what it did. The only way he could have avoided that screw from doing what it did was to avoid the screw all together; and since I wasn't there riding his bike I can't tell you if that was possible.
