Sorry but... Why are they a tag team? I mean, I know there are a lot of "for no reason" tag teams so I would like to know if there is a reason story or character-wise for the team.
Sandow said he had found his intellectual equal, or something to that effect in Rhodes, hence the tag team.
The non kayfabe reason for the team is that they have no singles plan for either guy right now, but want them to stay relevant, so they paired them up. Rhodes Scholars vs. Hell No will be a pretty interesting storyline in my opinion, I like both teams a lot.
What worries me is that with the joint titantron and name for the team, it seems they may be teaming for longer than I thought. Sandow is far too talented to be stuck in the tag team division for long, as is Rhodes.
