The Berlin Thunder were a professional American football team in NFL Europe, which was a springtime American football league serving primarily as a developmental league for the National Football League. Most of the players were young American professional players assigned by NFL teams to receive additional game experience and coaching. Coaching staffs are predominantly provided by the NFL for developmental purposes as well. In addition, "national" players, or non-American players, compete on each team. Berlin's 2006 squad included players from Germany, Finland, England, Mexico and Japan. Players and coaches had their living expenses paid for by the league while in Europe in addition to their salaries..
On April Fools Day 2006, the Thunder recorded their very first tie in franchise history. Trailing the Hamburg Sea Devils 17-0 at halftime, the Thunder erased their deficit to tie it up, going into overtime. Unfortunately, neither team could come up with a point in the extra period. This was only the second tie in the history of NFL Europe. The previous tie came in the 1992 season between the Birmingham Fire and the London Monarchs. The final score for that game was also 17-17.
