It's no surprise that Rick Grimes and ex-NFL player Tyreese meet early on in The Walking Dead comic. As fathers leading a band of survivors throughout a zombie apocalypse, their paths were bound to cross. Season 2 would be a perfect place to introduce Tyreese, along with his daughter Julie and her boyfriend Chris. Not only would it be interesting to see Tyreese and Carol's relationship play out on screen, adding another alpha-male into the mix would surely shake things up a bit.
