The months leading up to the NFL Draft can be a very stressful time for a prospect. Each movement or decision is heavily scrutinized and can have a major impact on a player's draft position. It seems that there are more opportunities to hurt a stock than help it.
Things like off-the-field issues, injuries and poor workout numbers can all have a disastrous impact. For example, Arkansas quarterback Ryan Mallett fell from a potential first-round pick to coming off the board in the third-round. His fall can be attributed to the many question marks surrounding his decision-making and maturity.
