Almost all of the rotation is back end guys right now. The red meat won't get here for a year or two, hopefully. That whole string of Shuster, Nastrini, Canon, Martin, Wilson, etc, are guys you hope figure it out and give you that 4.5 era over 160 innings to fill some innings over the course of seasons. Maybe a Burke has more of a mid rotation ceiling, but there just aren't those guys here yet.
