I was watching videos a few days ago of the Pairs Best Performance Awards at Nationals given by the US Professional Skating Association each year.  I watched Rockne Brubaker's 2008 FS with Keauna McLaughlin.  I was thinking about how suddenly Keauna retired and how young she was, when I wondered how old Rockne is now ... turns out he's 33 ... only a year older than Chris Knierim.
And my mind kept going ... Rockne could take 2 years away from his coaching to partner with Alexa.... hmmm.  I know, I know, it's not that easy, or even desirable to drop the teams he coaches and leave them in the lurch, and I wouldn't want him to, unless another coach could simply step in to work with Stefania.  But I've always regretted how Rockne quit earlier than it seemed he wanted; he couldn't get subsequent partnerships to last either. 
He's such an artistic skater, so in that way he wouldn't really match with Alexa; her talent is in the beauty of the elements, while Rockne's is more a fluidity of expression with his skating and his movement.  And also, he may not be tall enough, at least not for what she's used to.  But they'd look good together.
