But this year in Washington will provide us an interesting opportunity to see just how effective Callahan's scheme is.
"When you walk in the door you look at the players first and what they do best and you fashion a system around their strengths and their skill levels," he said, via CSN Washington.
Callahan might have his toughest starting point yet, with Kory Lichtensteiger and Trent Williams leading the way on the offensive line. Rookie tackle Brandon Scherff will also be one to watch. Despite being a top-five pick, there seemed to be more doubts about his readiness than there was with Callahan's last rookie project in Dallas, Zack Martin.
Another top 10 finish in rushing offense would certainly negate the naysayers that suggest Callahan is walking into gigs with premium talent. It would also be a godsend for Robert Griffin III, who is trying desperately to get his game back.
