"The boys are a little bit bewildered by it but we have to accept the referee saw something different."
Skipper Jerome Kaino, outstanding at No 8 in his milestone 100th match, thought Hoffman might have made the decision due to Luke Braid's backtracking from the lineout, yet Braid was in a halfback role at the set piece.
The Blues will have to look at how they found their way to that lineout. Up to that point, they had done well in playing for territory only to concede a scrum at which prop Sam Prattley was penalised for a clearly illegal bind. The resulting clearance was the beginning of the end.
A week earlier against the Stormers, they were as good as done when Hayden Triggs was sent off for punching. A week before that, two soft tries to the Chiefs left them with too much to do.
This one was cruel on the Blues, though, because in Kaino, Charlie Faumuina and Patrick Tuipulotu they had three of the game's outstanding players. Kaino, picking up the third try which put the Blues right back in it, was at his rampaging best. The busy Faumuina showed brilliant skills in taking Tuipulotu's offload one-handed to score and Tuipulotu himself was a constant danger.
Charles Piutau played well closer to the action at centre, and fullback Lolagi Visinia showed invention and aggression on the counter.
The Blues now have to pick themselves up and prepare for next Saturday's match against the Lions at North Harbour. With only two competition points, and a run of tough away matches to follow, they are in a deep hole.
Cheetahs 25 (Cornal Hendricks 2, Sarel Pretorius tries; Joe Pietersen 2 cons, 2 pens) Blues 24 (Luke Braid, Charlie Faumuina, Jerome Kaino tries; Ihaia West 3 cons, pen).
Halftime: 12-14.
