The decision to replace a veteran with a rookie as the starting quarterback is a rare happening in Vikings history.
You have to go back 50 years to the Purple's first season to find a comparable situation to what occurred this week, when coach Les Frazier informed Donovan McNabb that he was being benched in favor of Christian Ponder, the No. 12 overall selection from Florida State.
The Vikings had traded a first-round choice to the New York Giants for veteran George Shaw. He started the 1961 opener vs. the Chicago Bears, was hooked before the end of the first quarter and Fran Tarkenton arrived to lead the Vikings to a 37-13 victory.
Tarkenton, a third-rounder from Georgia, started the next week and 10 of the final 13 games.
Unless you choose to include Joe Kapp, a veteran brought in from Canada in 1967, Tarkenton was followed by four other rookie QB starters over the next 49 seasons: Ron VanderKelen in the 1963 season finale for Tarkenton; Tommy Kramer, one game for Bobby Lee (who had replaced an injured Tarkenton) in 1977; Tarvaris Jackson, the last two games for Brad Johnson in 2006, and Joe Webb for the last two games in 2010 when Brett Favre and Jackson were injured.
Ponder will be the first Vikings rookie quarterback to get a shot at starting with a majority of the schedule remaining in 50 years.
Ponder/McNabb will not stand as the greatest controversy involving a quarterback prospect and a much-acclaimed veteran with the Vikings. McNabb had been around for only six starts, and he moved aside Wednesday with little more than a whimper.
That was not the case in 1978, when Tarkenton -- a two-term Viking in his 18th NFL season -- did not fade away quietly as fans booed and called for Kramer to take over.
