Dobbins gets real about the Broncos’ offenseFollowing the 10-7 win over the Raiders at Empower Field at Mile High on Thursday, J.K. Dobbins didn't mince words about his feelings on the Broncos' offense. The running back believes it's time for the offense to live up to expectations, commending the team's defense.“Yeah, cool, we're 8-2 ... [but] the defense is winning us the games, and we’re not helping them. We’re not doing them any justice,” Dobbins said, via Jeff Legwold of ESPN.com.“I feel bad the way we play on offense and the way they play on defense because they’re doing so great and we’re doing so bad. They’re our brothers, too, and it just sucks because they’re just out there so many plays, playing their butts off. We can’t keep doing this to them.”The Broncos are averaging 341.2 total yards per game while scoring 23.5 points per game. However, it's the team's defense that has played a crucial role in the impressive start to the season. J.K. Dobbins himself has contributed 772 rushing yards (third in the NFL) and five touchdowns.
