Kerry Collins took a physical for the Titans yesterday. If he signs, that would be bad news for Billy Volek…because Collins has never been a back-up quarterback. Last season Collins started 15 games for the Raiders and threw for 3,759 yards with 20 TD passes and 12 interceptions. For his career, Collins has played in 152 games and completed 55.6% of his passes for 33,637 yards with 173 TD passes and 166 interceptions for a career rating of 73.8. Collins still has the big arm he always has had, and the thought here is that he would beat Billy Volek out and push Vince Young to #3.
