Dan Jackson on "light years" improvement between springs 1 and 2, spring roster studs, NDSU-to-FBS

Jackson told Sioux Falls Live's Matt Zimmer last week his football team is "light years" ahead of where it was last year during the early stages of spring football, and that the Jacks are "creating an identity." What is that identity?    How have Chase Mason, Chase Van Tol, Lofton O'Groske and other stars progressed — both in their health and skill set — since their injuries took a toll in a 9-5 campaign?   How much of difference does actually having a strength coach make? Who are some of the emerging fresh faces, especially at running back, where Jackson is excited to have the "home run hitter" the Jacks lacked last year?   And, yes, does NDSU's climb into the Mountain West make Jackson want to lead the Jacks to the "next level?"
