Yeah that sounds dumb actually.
I would like to see more play between Rogers/Walker...though, just always felt there was unresolved issues there. It was like Marvel was so embaressed of the Walker Saga that it was taboo for Walker to appear in the pages of cap henceforth. Even though Walker was almost immediatly put to use in West Coast Avengers after that arc.
Some people at Marvel obviously see strengths in Walker, becuase he's been fairly heavily used over the years(though not really developed)...all things considered.
