'The Walking Dead' casts important new character for season 3

The third season of AMC's zombie apocalypse drama The Walking Dead has been rather surprisingly consistent; there hasn't been an episode this season that I would consider weak (though I was rather chafed by the questionable departure of T-Dog a few weeks ago). 

Part of what has buoyed this season to such heights is the introduction of new characters from the comics upon with the show is based. Most notable, of course, are the introductions of the sword-weilding Michonne (Danai Guirira) and the unhinged-yet-charismatic Governor (David Morrissey). Now, it appears, the series is prepared to introduce a third major character from the comics -- Tyreese. 

Tyreese, for those who haven't read the comics, is a former NFL linebacker who becomes Rick's second-in-command during his time at the prison. Tyreese, who is accompanied by his daughter and her boyfriend, is a reliable advisor to Rick, though like everyone, he struggles at times to cope with the traumas the zombie apocalypse forces upon them. 

Tyreese will be reportedly portrayed by Chad Coleman, an actor perhaps most famous for playing Dennis "Cutty" Wise on the critically acclaimed HBO drama The Wire. It's unknown how Tyreese will be introduced into the storyline -- some speculate he will be a member of the Governor-led Woodbury community -- but it's expected that he will make his first appearance on the series in the midseason finale, December 2's "Made to Suffer." 

What do you think? Is Coleman right for the role? What role do you expect Tyreese will play in the television series? 

The next episode of The Walking Dead, "When the Dead Come Knocking," airs Sunday, November 26 at 9/8c on AMC.
