I'm totally biased, of course, but to me it's Troy no question. Put him on those Niner teams in that WC offense, and he'd have put up the same or better numbers as Young. And of course, I'd trust Troy with the game on the line more so than Young. And here's a case where the whole question of "how many rings does he have" is valid -- it ain't like Young played on some half-baked team with no supporting cast and poor coaching. He had phenomenal talent around him, a great coaching staff, and an offense perfectly designed to fit his and his teammates' skills. Young - genuinely great player. Troy - even better.
