The biggest obstacle facing the Minnesota Vikings this week may be mental.

The Vikings have to shake off the effect of a tie that felt like a loss after kicker Daniel Carlson missed a pair of field goals in overtime in the 29-29 stalemate against bitter rival Green Bay.

Minnesota also has to avoid the temptation of looking past the visiting Buffalo Bills, who arrive in the Twin Cities off lopsided losses to the Baltimore Ravens and Los Angeles Chargers in which they were barely competitive.
