If you are looking for a hail mary RB play this week, take a look at UTEP's Joseph Banyard, who has struggled for the most part in 2011, but has the skills to have a huge game against Rice.
The Rice defense has allowed a C-USA-worst 206.5 rushing yards per game this season and was shredded all over the field by Houston last week. He is a decent desperation play if you need one.
