What is the general opinion of:

Jeremy Jeffress (RHP-MIL)

Brad Lincoln (RHP-PIT)

Phillippe Aumont (RHP-SEA)

Jeffress definitely has the highest ceiling, and has dominated A+ hitters since he was demoted from Huntsville.  The Brewers continue to claim his future is in the rotation, even though his fastball profiles best out of the bullpen.

Lincoln is the best PITCHER of the bunch, and is having the most success at the highest level.  However, he also comes with the red flag of his past surgery.  So far, he would seem to be the safest bet amongst the three to stick in a rotation (and not only because he's a Pirate pitching prospect).

Aumont is languishing in the bullpen in A+, and the Mariners have not shown a willingness to move him out of this role either.  However, anyone who has seen the way the Mariners have handled Brandon Morrow knows that sticking him in the bullpen may not be permanent.  Being deployed in shorter spurts allows his stuff to play almost up to the level of Jeffress (though Jeffress has arguably the best fastball in all the minors).

Thus my question is, between these three, which one is the most valuable to an organization?  The starter languishing in the bullpen?  The closer languishing in the rotation?  Or the pitcher with the heightened risk of injury?  I would probably go with ceiling, but it is not as if Lincoln is without a good ceiling.  If given the choice, which TINSTAPP would you prefer?
