I refute the Second Paragraph with the Cap-Prometheus fight during the final showdown of Avengers/JLA: "Neural Chaff, Hypnotic Lights, Pre Programmed Fighting skills. Try fighting the Werhmacht mister, it teaches you focus!" The easy one punching of someone who I would likely guess is the original Prometheus shows that Cap can avoid the distractions. Also we are assuming that Cap gives Bats enough time to get to the belt, after the first projectile gets thrown I'm guessing that Cap won't let his hands get close enough to use another one.
