They were odd, but they were not "bad". I actually see Nomo and Lincecum having similar "cues". They both turn their back to the hitter (leading with the hips), have a great deal of hip/shoulder separation (flexibility required), have a backwards lean at lead foot plant (results in a high, straight over the top release point). With such a release point, they both have to get their heads out of the way, though.
Nomo was slow in his delivery before breaking his hands, but after that he had good tempo and explosiveness.
I like Santana's mechanics as well. Very simple and repeatable.
