I'm not sure if they could right away, but I'm willing to bet there are some QB's that if you worked with them on mechanics for a couple months, they could be throwing 90 mph. There's a pitcher on UCD's baseball team who is a fifth-year senior and hadn't played baseball since he was a junior in high school and when he did play, he was a catcher. He went to UCD as a water polo player and after his senior season ended in that sport, he decided to try to walk on to the baseball team. He had a couple former UCD players (guys he went to H.S. with) teach him how to throw over about a six week stretch and made the UCD team. He can reach 90 mph on his fastball. Like I said, I doubt that every NFL QB could, but it wouldn't surprise me if some were able to. Of course, they'd probably have to work as relief pitchers at first to build the arm strength up to throw 90-100 pitches. I'm not sure what point you're trying to make. I didn't say a QB couldn't throw a baseball 90 mph. I'm not really sure how that applies here.
