He had 31 catches in his rookie year - Naz Mitrou-Long Jersey - good for 15th amongst first-year players. His 294 receiving yards were 19th amongst all rookies and his three touchdowns were tied for 11th. The seventh-round pick was set to battle for a roster spot in training camp, but has found his way into the starting lineup after a week of practice. What's even more surprising is that free agent signing and 2020 fifth-round pick K.J. Osborn aren't ahead of Johnson on the depth chart either.Why is Jefferson the No. 3 wide receiver a big deal in Minnesota? The Vikings don't run many three-wide receiver sets to begin with, running "11 personnel" just 25% of the time last season () -- the lowest percentage in the NFL. Minnesota ran "21 personnel" (two running backs) 21% of the time -- second in the NFL -- and "12 personnel" (two tight ends) 34% of the time, also second in the league.If Jefferson is the No. 3 wide receiver in Minnesota, he isn't getting on the field much. Jefferson was arguably the best slot receiver in college last season, but the lack of "11 personnel" hurts his chances with the Vikings unle s offensive coordinator Gary Kubiak adds a new wrinkle to the offense different from Kevin Stefanski.Whether Jefferson is a good fit with the Vikings remains to be seen, but he still needs to acclimate himself to the offense. doesn't appear too concerned with his progre s."I think he's just doing a nice job here getting the play call in the huddle, getting out, getting lined up, knowing where to go, what to do, the depth to go on the route and ultimately why you bring him in is for the natural stuff," Cousins said. "Learning the plays takes time no matter how good you are, but when the instincts can take over and you can make great plays, that's what you're looking for." Reggie Miller Jersey
