Homicide: Life on Repeat

At first, I was thrilled to see Andre Braugher would be getting a six-episode arc on ER next season (the perfect length to still qualify for a Guest Actor in a Drama Emmy). But then I read on:

Braugher ("Homicide: Life on the Street") will appear in a six-episode arc as a carpenter who arrives in the emergency room with a simple cough. But he suffers a stroke while waiting to be seen, and his life eventually falls apart as a result of his paralysis.

Uh, hasn't he already done that storyline? As always, he was amazing, but I'd rather see him show us something new. However, any Braugher is better than no Braugher at all (unless it's in Poseidon), so this is still enough to get me to tune into ER again.
