Should I Kick These Two Out Of Fantasy Football League?

Ok, so there was a trade made in the fantasy football league that many other people in the league are not happy about. As the league manger what should I do? Should I let them stay or should I kick them out of the league?

So basically Los Angeles Soldiers traded two top 10 RB's and a top WR for bunch of backups. What you should know i that these guys are brothers.

So what should I do? Kick 'em out or let 'em stay?
