I would think these programs all offer rotations. I know U Colorado @ Anschutz does 3 rotations and doesn't require TA/teaching (that campus doesn't have undergrads). I didn't attend but my boyfriend did his PhD at Anschutz in the structure & biochem program. He loved it and it sounds like they have some incredible research there, but he has always said it's a much more chill, work/life balance environment than some of the more "name brand" coastal schools. He wound up at a top post-doc and has solid papers from grad school, so clearly they still get the work done, but it sounds like a different sort of vibe than the other schools you listed.
