Mankin is and will be a nice solid player. However it isn't likely that he would see the floor before Woodard, Buddy, Cousins, Hornbeak, Cam, Spangler, Bennett, Cam, or Tyler. If we need a guard, Booker would get in 1st. If we need a big, Hamilton would be in 1st.
He has gotten a lot of work over the last few weeks with the 1's and 2's. Kruger has been getting him ready to be ready in case he is ever needed. I think he will be. He is probably a year away from being as good or better than Tyler. That might not be good enough to make the 8 man rotation even then.
