David Johnson: Cardinals Can Be Best Offense in NFL with Sam Bradford

Arizona Cardinals running back David Johnson has high expectations with Sam Bradford leading the offense in 2018.      

Appearing on SiriusXM's Mad Dog Sports Radio on Wednesday, Johnson said the Cardinals will have the best offense in the NFL if the quarterback stays healthy:

"We're going to be great if Sam Bradford is healthy. ... For me watching him personally I've seen him do some great things. I think the biggest thing is just being healthy. Not just with the addition of him but also the linemen we got, the receivers and everyone else that we have added to the team on the offensive side, I think we definitely will be the top offense in the league this year."

Bradford appeared in just two games for the Minnesota Vikings last season and had his knee scoped in November before being placed on injured reserve. 

Following Carson Palmer's retirement, the Cardinals signed Bradford to a two-year deal worth up to $40 million in March. They finished 22nd in total yards per game (314.1) and 25th in points per game (18.4) last season. 

Dating back to his college days at Oklahoma, Bradford has struggled to stay on the field. He played in just three games as a junior in 2009 because of a shoulder injury. 

Since being selected No. 1 overall by the then-St. Louis Rams in 2010, Bradford has only played a full 16-game schedule twice in eight seasons. The 30-year-old led the NFL with a 71.6 completion percentage and threw for a career-high 3,877 yards in 15 games during the 2016 season.
