To blindly blame or not blame a star player is dumb either way. But whenever a star player is justly criticized for his performance if he doesn't perform in a losing effort, there is always, always always always a contingent of people who completely ignore the fact that he didn't perform up to par, and use the "it's a team game" cop out. And those same people are the ones who will turn around and anoint someone as a demi god and give that star player all the credit for putting up ridiculous stats or winning.
How can you say Marino never had help on his Dolphins teams? He had a career .613 winning percentage. They got it done in the regular season, but folded when it really mattered. So it's okay to praise him and give him all kinds of glory for all of this:
and use all of that as reason to call him one of the greatest of all time, but when they lose, and he doesn't get the job done, then his performance is irrelevant because it's a team game? His team and his running game was reliable enough to help him achieve all of those regular season awards and stats and records. I'm just saying, be consistent about it. There's no point in circling the wagons.
The QB is the single most important position in maybe all of sports. It isn't ALL on him, but it's fair to criticize someone who puts up all of those stats and all of those wins in the regular season, and then doesn't replicate it when the lights are at their brightest. Especially when you look at it game by game. Now I wasn't old enough to really recall specifics of Marino's career, but I vividly remember all of Peyton Manning's one and dones, all 9 of them, in fact.
I vividly remember him running roughshod over the entire NFL in the regular season, year after year, winning MVP after MVP, leading the league in every stat imaginable, breaking records left and right, only to lose at home in the first round of the playoffs to a lower seed and have nothing to show for it. And not only lose, but lose putting up very very low point totals, in some cases even getting shut out completely. The excuse making for Peyton Manning is unbearable. He finally broke through that one year and won it all, but that year has been the exception, not the rule, for his whole career.
