Henne has Marshall in his prime and one of the best slot receivers in the game. Kitna has been putting up numbers his entire career. In fact before he was hurt in Detroit he was well on his way to being the 20th quarterback of all time in terms of yards. Miami did have the appropriate talent to meet Henne's skill set. Henne hasn't shown the appropriate skills to take advantage of the talent. You also mention taking away Ginn, however he barely threw it deep to him either.
