Poll: Big Ten's most irreplaceable non-QB

Bruce Feldman is taking a look at the nation's most irreplaceable players who don't play the quarterback position. The Big Ten undoubtedly has several signal-callers who are vital to their team's success -- Nathan Scheelhaase, Dan Persa, Denard Robinson, Kirk Cousins, Taylor Martinez and Russell Wilson, to name a few -- not because of their ability on the field but because of depth issues behind them.

Which non-quarterbacks can Big Ten teams not afford to lose in 2011?

Feldman identifies two players on his list: Nebraska DT Jared Crick and Michigan DT Mike Martin. He ranks Crick at No. 2 overall behind Alabama RB Trent Richardson, while Martin checks in at No. 7. The two interior linemen both have NFL potential and will anchor their respective defenses this fall. Martin would be extremely tough to replace, and while Nebraska has more depth up front, Crick would be a big loss as well.

Who else fits into this category? Wisconsin linebacker Chris Borland comes to mind. Iowa left tackle Riley Reiff would be a significant loss. Same goes for Ohio State center Mike Brewster, a four-year starter.

Now it's your turn. Vote for who you think is the Big Ten's most irreplaceable non-quarterback. Remember, think about depth at the position in addition to quality of the player being mentioned.
