I thought players were allowed only 1 undergrad transfer and 1 grad transfer without sitting out a year?
Mackus answered part 1 of your question, but the answer to part 2 is that even before the recent WV court injunction there were no restrictions on grad transfers. They can transfer as many times as they wish (provided they still have eligibility) and are also not subject to the portal windows (so they can enter the portal any time they want).
