We've already looked at the big shoes to fill throughout the Big Ten in 2010.

So who steps in this fall? Here are five newcomers to watch.

Penn State QB Kevin Newsome: All the candidates for Penn State's starting quarterback job -- Matt McGloin, Robert Bolden, Paul Jones -- could be listed here, but Newsome saw the most action in 2009, appearing in 10 games. Penn State hoped to get Newsome more field time, but he showed good mobility with two rushing touchdowns and completed 8 of 11 pass attempts. His development during the winter and spring will be critical as Penn State looks to replace Daryll Clark.

Purdue QB Robert Marve: The Miami transfer finally gets his chance to compete for the starting job as Purdue must replace the productive Joey Elliott. Marve sat out the 2009 season, though he would have missed most of it with an ACL injury. He hasn't been on the practice field much at Purdue, but he'll be viewed as the front-runner for the top job along with Caleb TerBush.

Ohio State RB Jaamal Berry: Ohio State fans clamoring to see Berry since early last season will finally get their wish. A hamstring injury kept Berry from playing as a true freshman in 2009, but he'll be ready to push Brandon Saine and Dan Herron for the starting job this year. Though both Saine and Herron performed well down the stretch and in the Rose Bowl, Berry comes in with impressive credentials and could have what it takes to become a featured back for the Buckeyes.

Michigan CB/S Demar Dorsey: His signing generated plenty of controversy at Michigan, but there's little doubt Dorsey will be an impact player this fall. Michigan desperately needs to upgrade its secondary, and the heralded Dorsey will compete for immediate time, first at cornerback and possibly at safety down the road. Dorsey brings tremendous athleticism and a willingness to bring big hits on ball carriers.

Michigan State LB/DE William Gholston: The Spartans' defense regressed in 2009, and Gholston will have an immediate opportunity to contribute. Gholston is a unique specimen at 6-foot-7 and 237 pounds, and the heralded recruit should be able to help Michigan State's pass rush from an outside linebacker or rush-end position. It'll be interesting to see how the Spartans coaches use Gholston in 2010, but he'll undoubtedly have a major role for the defense.

Five more to watch: Michigan QB Devin Gardner, Iowa TE C.J. Fiedorowicz, Illinois QB Nathan Scheelhaase, Indiana CB Andre Kates, Penn State LB Khairi Fortt
