CAPs were working OK at first. I always create my fantasy team right away. I have 13 CAPs saved.
You can save DNA but there was a limit (5 or 6) last year. Not sure this year.
For my fantasy team I create the CAP, export the DNA, then import the DNA over a scrub free agent. I do this to avoid the nickname commentary. But this approach would let you create multiple CAPs and apply the DNA to several scrub fee agents as a work around.
