Yeah everybody's going to say the Turpin family, but in light of last night's events, I think it would be very interesting if they did an episode where a woman's raped at a Super Bowl party and the most likely suspect is a guy whose team lost. L&O has done episodes about sports rage driven attacks/murders by athletes, fans and little league parents alike, so why not one that looks at the idea that Super Bowl Sunday is the most violent day for women? Because whether you believe it or not, that's what the show does, they (used to anyway) look at all angles.
Wouldn't be bad, perhaps throw in a twist a suspect is arrested, the typical greasy ex-con from downstairs is the prime suspect, then the real rapist turns out to be her friend, mad because his team lost.
They should do an opening filler shot of Rollins dressed as an Eagles cheerleader at a SB party, then a cut to Olivia and Barba drinking in a bar where Olivia says "this is the only place in the city where we don't have to listen to sportsball"
The episode I really want to see though is the one where the deconstruct Stabler.
Also might be interesting to do a crossover with Criminal Minds, or even perhaps bring some of the cast from The Wire, after all L&O crossed over with Homicide a few times, and it would be a good way to have Munch return for an episode.
