Navy has scored a minimum of 31 points in eight of its last nine games. Thanks to QB Malcom Perry, the Midshipmen led the nation in rushing. I don't see Kansas State, with a below average run defense, being able to slow down Navy's option attack. It's Navy's relentless ground attack that wears down opponents not the other way around. 
But Kansas State has the skill position athletes and Big 12 pedigree to take advantage of Navy's defense. Wildcats QB Skyler Thompson is a dual threat accounting for 22 TD's this season while passing for more than 4,000 yards and rushing for more than 1,000 during his career. 
Navy has to look out for Joshua Youngblood, too. He was the Big 12 Special Teams Player of the Year. Youngblood has brought back three kicks for TD's in the last four games.
