Question Twisted character models when applied to TPS BR animations

I've been playing with TPS BR to practice network technologies and was stumped when trying to use the provided animations on a new character model. I created a simple animation controller that just goes to a jogging animation and when I apply it to the new model it gets twisted in weird ways.



I've tried various things, like redoing the bone axis and re-exporting from blender, to renaming the bones to match the previous rig's bone names, to trying various rigging options in unity. I just can't seem to find why different portions of the model are twisted in weird ways, like the head turning about 90 degrees.

Any help would be appreciated, thanks!

UPDATE: It looks like the bones in the model that was given has a bunch of crazy rolls in the bones. In turn, this gave a lot of weird rotations to the animations that were provided by TPS BR. Instead of updating the animations I attempted to add the same rolls to the bones in the new model, but that still gave weird deformations. Instead I took the rig out of the original model and added it to the viking model in Blender and I at least got something passable.

I'm going to keep going down this route just to get something up and running to test, but if someone has a better was to match up this model to the animation I'd love to know the proper way to do it.
