David Duchovny tried to land all three of the male lead roles on Full House.

I can't see him playing any of the main male characters.

God bless you and him always!!!

P.S. He could've been one of the guys that took an interest in Becky though before she and Jesse got married and actually there were two episodes that included a guy that Jesse got jealous of before him and Becky tied the knot. At the end of season two she is shown with a guy named Todd Masters who was a big-time actor guest on Wake-Up San Francisco. David could've been that character, or he could've been the guy who took Becky to the cultural arts gathering in season. Jesse most definitely got insecure then because of his not having any college education in his background. I can't see him being Becky's rich cousin who paid her a visit during season six.
