The NFL depth chart is a fickle thing. The order constantly shifts week-to-week depending on individual performances from the most recent game, injuries suffered and the strength of the upcoming opponent.
In the case of the 2012 Minnesota Vikings, any prediction will be extremely difficult with the roster currently at the NFL maximum 90 players—46 of them who were not in Minnesota last season. That should not be a surprise for a team that finished 3-13 and is in the process of rebuilding.
The opening day roster for the Vikings will have a considerably different look to that of 2011.
Gone are 12 players that either opened the season in the starting lineup or had significant playing time.
This includes both starting guards, Steve Hutchinson and Anthony Herrera, tight ends Visanthe Shiancoe and Jim Kleinsasser, wide receiver Bernard Berrian and the opening day quarterback, Donovan McNabb, on offense.
Defensively, the Vikings are without cornerbacks Cedric Griffin and Asher Allen, safety Husain Abdullah, middle linebacker E. J. Henderson and defensive tackle Remi Ayodele.
Place-kicker Ryan Longwell, third all-time in scoring for the Vikings, has also been released.
While any attempt to predict the Vikings depth chart at this point is an exercise in futility, that's not going to stop me from projecting the team's starter and primary backup for each position.
