I'm no pitching analyst, but I've heard that the arm angle and the higher delivery point of the pitch can be a factor in the effectiveness of taller pitchers too. Is that true or another nonsense argument?

Driveline's article talks about it. Basically, there are ways to get efficiency from throwing motions. Longer levers (arms) require more torque/power to accelerate them, but that's offset by higher relative velocity (same throwing motion over the same amount of time for a long arm means the hand/baseball is traveling faster).

There's also an inherent PERCEIVED velocity as the taller the pitcher is, the longer their legs and arms and the closer to the plate they can be when they release the ball (extension). It doesn't make the ball travel any faster, it just makes it feel faster.

I'm not impressed with thre Driveline analysis, using a whopping sample of two pitchers. In any event, the analysis doesn't disprove the laws of physics. Arms and legs are levers. Longer levers possess more potential energy. Driveline doesn dispute that.

There are other factors in achieving velocity. I never denied that. In fact that has been my point. Ober seems to lack the ability to efficiently transfer potential energy to kinetic energy. Again, I'm not asking Ober to be one of the hardest throwers in baseball. I'm asking him to be just below average. Right now he's 5 mph below average.

It's physics. It's based on physical and mathematical laws, not 2 pitchers. The 2 pitchers were used as an example. I'm more impressed with Driveline's published findings based on mathematical law than your personal opinion so I'll stick with Driveline.

Thanks for that. I think that "perception" of velocity can actually be a factor in the effectiveness for pitchers like Ober. Whatever helps to deceive the batter or put him off balance is a plus.
