1. Trent Dilfer (2000): This is a no-brainer. The free-agent addition took over for the struggling Tony Banks midway through the season. After losing his first start, Dilfer won his next 11 including the Super Bowl triumph over the New York Giants. His statistics were never stellar -- his regular-season quarterback rating was 76.6 -- but his impact was far from mediocre. (Note: Bulger will sign a one-year, $3.8 million contract, which is nearly four times the deal that Dilfer signed. In March 2000, Dilfer agreed to a one-year, $1 million contract).
