Here, we'll take a look at a couple of key players going, staying and coming for each team in the Big 12.
Jesse Smith, LB
Smith leaves after leading the Big 12 in tackles in 2009 with 135 stops. Smith was one of three linebackers the Cyclones lost entering 2010. A.J. Klein, Matt Tau'fo'ou and Jake Knott will be among those to step in as new linebackers.
Christopher Lyle, DE
Lyle had a team-high five sacks in 2009 and 13 tackles for loss. He was also fourth on the team with 88 total tackles, just four less than James Smith, the Cyclones' No. 2 tackler.
The Cyclones also lose Marquis Hamilton, their leading receiver, who caught 50 passes for 606 yards and four touchdowns.
Robinson was an honorable mention All-Big 12 performer in 2009 with 1,195 yards rushing, third most in the Big 12. Entering 2010, coach Paul Rhoads will certainly look to get Robinson the ball often once again this season. Robinson had 232 carries last season and averaged almost 99.6 yards per game. He topped the 100-yard mark in six games as a junior.
Austen Arnaud, QB
Arnaud's numbers slipped in 2009, and he'll be ready to improve on those as a senior. Last season, his completion percentage slipped below 60 percent and he threw 13 interceptions, but Arnaud accounted for 22 touchdowns.
Jeremiah George, LB
George ranked as the No. 53 outside linebacker in the country and could try to compete for time in a linebacking corps without a lot of experience. A Clearwater, Fla., native, George is a stout 200 pounds and stands at 5-foot-11.
Chris Young, WR
Young is just 5-foot-11 and 185 pounds, but comes to Ames as one of the top JUCO receivers in the country. If Young can help add some game-breaking ability to the Cyclone' offense, he could see the field immediately.
