Matt Patricia took a mediocre team and made it a lousy one in his first two seasons. If things don’t improve dramatically this year, especially on defense, Patricia is a goner.

The Minnesota Vikings signed head coach Mike Zimmer to a three-year contract extension through the 2023 season, finalizing a key piece of business Friday before the beginning of training camp. Zimmer has a 57-38-1 record over six years, the third-best winning percentage (.599) of the nine head coaches the franchise has had over 59 seasons. The new deal, which was agreed upon earlier in the week, was hardly a surprise for an organization that has prided itself on stability since owners Zygi Wilf and Mark Wilf took over in 2005.
