The first week of our countdown to spring football is in the books, with the defensive line anointed as the position group with most room to improve at Nebraska.

This week, we will count down the top five players to watch in spring practice, which begins on March 8.

First, a few ground rules: This is from my perspective, not the perceived view of Bo Pelini or his staff. I don’t sit through meetings or receive access to watch every snap of the 15 practices set for March and April. As a result, my criteria for inclusion on this list is no doubt different than the benchmarks of, say, offensive line coach John Garrison.

We’re looking for potential breakout players -- the Cornhuskers most likely to take a big leap in 2014, or, at least, those whose progress could most make an impact the program.

With that, let’s get started with a second-year Husker whose playmaking ability could help the Nebraska offense in many ways:

Sophomore I-back Terrell Newby

Why to watch: Newby earned his spot as the No. 3 back last year behind veterans Ameer Abdullah and Imani Cross. And while all three return, Newby might actually stand in line to receive the biggest jump in playing time from last season to the upcoming one. Sure, Abdullah is the workhorse and an All-America candidate, but Newby averaged 5.5 yards on 54 attempts a year ago. His responsibility could increase significantly in 2014, even among a crowded backfield.

What to watch: Newby has more to offer, especially in the passing game. He caught just three passes last season, but these offseason practices serve as an excellent opportunity for the Huskers to incorporate him as a versatile threat. The Huskers aren’t likely to reveal any secrets in the Red-White game, but what would you think of Newby as an option in the slot? The Huskers are intrigued by his athleticism and will look for ways to utilize it.

What to expect: There was a temptation here to go with Adam Taylor, a big redshirt freshman back from Texas who wowed Nebraska coaches and teammates on the scout team last fall. But really, that’s just a fascination with the unknown. Newby is the more proven option -- and the guy most likely to serve as an x-factor for the Nebraska offense. He might find an increased role on special teams and, by August, provide many ways to alter the game. This spring is just a preview.
