I think the most relevant question here is whether the Griz staff had one or more backup options in mind all along or if they would have preferred Britt to realistic remaining portal options.
If they were only comfortable losing Britt in a scenario where Tuttle transfers in, this would be the worst possible outcome. Tuttle only teased enough to chase Britt off, and then backed out.
However, if the staff knew all along that there was portal option B, C, D, etc. that they'd prefer over Britt anyways, then this is unfortunate but not devastating.
