Trick plays don't necessarily tell a player that they can't hang with or beat a team straight up. Trick plays are designed to catch a team off guard and make them 'think' rather than 'react'. If anyone watched FSU in the 80's & 90's and they played a tough opponent in the regular season or bowl game, Bowden would pull a few trick plays out of his hat. They would almost always end up demoralizing their opponent. Since the opposing defense would be in thinking mode as opposed to react mode.
