The Vikings' D-line in 2014

In looking ahead to the 2013 season, the Minnesota Vikings appear to have a pretty strong cast of characters on the defensive line, with DEs Brian Robison and Jared Allen sandwiching Kevin Williams and Letroy Guion at DT. Throw in DEs Everson Griffen and Lawrence Jackson as well as first-round pick Sharrif Floyd at DT, and it's a fearsome group. The only problem is, the future is not nearly as certain, given the current contracts on file.
