In college we don't, at least fans don't, have all the fancy stats like we do with the pros. We have certain numbers but a lot of it is the eye test. Early break vs late break vs no break. Run to the right vs run to the left vs no run at all. For change ups especially it is release point that is important (trying to make sure it is the same as your fastball). Velocity difference definitely is important. Nola is a very polarizing pitcher because while his plus command is evident his stuff is debated. Heck, here are two different write ups on his spitches: Mlb.com: 60 fastball, 50 slider, 60 change up. Nola isn't physical or overpowering, but he has exquisite command of his three-pitch arsenal. He effortlessly works at 91-93 mph with his fastball, which plays up because his low three-quarters arm slot produces sink and he can locate the pitch wherever he wants. His changeup is his best secondary pitch, grading as plus at times, and he can throw his three-quarters breaking ball for strikes. Espn.com 55 fastball, 60 curve ball, 50 change He gets downward movement on his 91-93 fastball, giving right-handed hitters fits and gets plenty of ground balls. His curveball is a potential swing-and-miss pitch in the mid 70's with good depth and spin, and he has good feel for the pitch as well. Right now Nola's change is just average, offering some fade but inconsistent arm speed hurts the deception on the pitch. Both credible sources with two very different write ups. Not only do they disagree on Nola's best secondary pitch but what his breaking ball is. One thing to be noted is I don't believe any of the grades have been changed since they were first written up. One example of why I say that is because here is a line from an article Law/Crawford did together last week: "Usually, pitchers who have arm-slot issues don't belong in a discussion of prospects with the highest floors, but Nola is a rare exception. He has two plus pitches in a 92-94 mph fastball and a change that has quality deception from arm speed, and he commands both of those offerings from his low three-quarter arm slot. "
