The Vikings may be on to something that the Redskins were onto last year. According to ESPN:
The Vikings have been evaluating Donovan McNabb‘s mechanics this week, a response to some inaccuracy issues that have bogged down the 34-year-old and the Minnesota offense.
McNabb has only one turnover, an interception on his first play from scrimmage off a batted pass at the line, through three games. His predecessor, Brett Favre, had seven by this point last season. But several of McNabb’s throws have been uncatchable, either one-hoppers that landed well short of receivers or air balls that sailed over the heads of his targets. That has been one big reason why the Vikings (0-3) haven’t been able to build on their halftime leads.
McNabb ranks 26th in the league with a 78.1 passer rating. His completion percentage is only 58, though that’s close to his career average. He’s shown he can still scramble and either hustle for a first down or hit his target while rolling out, but as long as they’re unable to complete any deep throws, McNabb and the Vikings can’t afford those medium-range passes to fall incomplete.
“The margin of error in our league is so thin that when you have a chance to hit a receiver or to make a catch, you have to do it because you just don’t know when that turn is going to come around again,” coach Leslie Frazier said.
