I was just looking from the standpoint of an established tag team. If they won the tag team championships, the WWF might of pushed them strictly as a tag team. If Shawn wouldn't comply, then I guess he would be out of a job. He was still green anyway. Thats just how I look at it.
Michaels wasn't green by the time Rockers appeared in WWE, FFS... They worked their fucking asses off and had sick match after sick match with pretty much everyone they faced! They'd already been teaming in AWA and other territories to some degree of success. (Note: Their 1988 WWF debut wasn't ACTUALLY their debut.... They debuted a good 18months before that but caught heat immediately and went 'territory' again until Vince came calling for the second time.)
Michaels and Jannetty had an understanding that they both always wanted to go singles eventually.... Jannetty may have lasted longer than he did as a singles guy in WWE too were it not for booze & drugs (He was no HBK, but he could have maintained a sweet mid-card run given his working abilities and beleive it or not at the time was superior to HBK on the mic).
As for the Rockers winning the titles, this happened on Saturday Night's main event late 90/early 91... The ring ropes broke, thus screwing the match up and leaving WWF no choice but to reverse the decision in the following weeks.
Notably, they never got another title shot and pretty much became jobbers until 'The Barber Shop Incident'.
