Calling all Tigers fans...

Question for you all in Motown.  I see that Porcello signed, congrats.  However, I have two intriguing picks that I can't seem to find out much on...Your fifth and sixth rounders, Casey Crosby and Cale Iorg.

Crosby really came on his senior year, sprouting up four inches and adding five mph to his fastball.  I know he was hurt his sophomore year, and he sat out most of his junior year.  BA had him pegged as a possible first round talent, but he fell due to signability (Full ride to Illinois).  How do you project the kid?  I drafted him in my Strat league, knowing he has some upside, but I don't know much more than waht MiLB.com provided in their draft preview.

Cale Iorg played for Bama, and he has MLB bloodlines with both his dad and (I believe) his brother playing in the bigs.  I know he took off a year for a missions trip, and he had an offer to start SS at ASU next season.  How does he project?  Is he a defensive player?  Is he an offensive player?  What are his primary skills?

Any info any of you can provide me would be of great assistance.  Thanks in advance!
