I think it would have been better for him to stay in retirement, but I don't it's fair for anyone to say he shouldn't have come back. If someone thinks that playing a couple lousy seasons at the end of his career can somehow tarnish what he did in his prime (and most of his career), then they are sorely mistaken..especially given what Michael Jordan had done. If someone wants to focus on the last two years of his career instead of all the amazing years before them, then that's on them, but in no way does it ruin or taint what he had already accomplished.
