I know that you will twist logic to fit your narrative but when the great and the good of football say that Benitez didn't have enough time, I'll take their word over a biased Sunderland fan. Carragher said, before Benitez had even taken charge of a game, that he's unsure there were enough games left as Rafa isn't firebrand motivator, he'd need time to turn the ship around.
We went down because we accrued insufficient points over 38 games to end the season outside the bottom three. You can point at 3 games if you like but that's cherry picking at it's worst. We would have stayed up had McClaren beaten Villa and not lost to you, or prevented Everton and Watford from doing the double over us, and so on.
It's revisionist to declare that Rafa was to blame for our relegation, just as it's revisionist to declare that sunderland sent us down.
I understand why you would try to manipulate the facts to show either of these things though, so if it helps, you crack on old boy.
