Summer is a time in college football where the only news is usually bad news. With that in mind, we're looking at the most indispensable players on each Big Ten team.

By indispensable, we don't necessarily mean best. We mean the players who would be hardest to replace between now and the start of the season if they got hurt/suspended/encounter Sharknado. That could be because of their value to the team or because of a lack of depth at their position.

We'll pick two players from each team, usually offense and defense, but not always. The series wraps up Wednesday with the Nebraska Cornhuskers.

Randy Gregory, DE, junior

This selection won't surprise Nebraska fans who fell in love with Gregory during his first season with Big Red. Few defenders have to be accounted for on every play, but Gregory does after leading the Big Ten in sacks (10.5) and tying for second in tackles for loss (17.5). Gregory recorded nine sacks in league games, including three in a road win against Michigan. He led the team with 18 quarterback hurries and recorded a pick-six, a fumble forced and a fumble recovered. Nebraska's defensive end depth isn't great as Avery Moss serves a year-long suspension, and while Greg McMullen looks promising, Gregory undoubtedly is the linchpin. Nebraska's defense needs No. 44 on the field to continue its progress from late last season.

Kenny Bell, WR, senior

Bell no longer has the Big Ten's most indispensable 'fro, but his value remains high for the Huskers. He's one of the nation's most experienced wide receivers with 134 career receptions for 1,901 yards and 15 touchdowns. Although his yards numbers went down from 2012 to 2013, his receptions total went up. Nebraska loses Quincy Enunwa and likely will rely more on Bell, who not only gives quarterback Tommy Armstrong Jr. a proven target but provides excellent perimeter blocking skills for Ameer Abdullah and the run game. Nebraska is still waiting for Jamal Turner to blossom. Jordan Westerkamp and Alonzo Moore are young and Taariq Allen hasn't been in a featured role. Bell contributes in so many ways and would be missed if he's not on the field this fall.
