The protoavis theory was actually rooted in the denial of dinosaur - bird relationship, and postulated that bird actually evolved separately from another as yet undiscovered branch of archosaurs family, maybe closer to alligators, well before the development of first dinosaurs. But it has been pretty thoroughly discredited by recent discoveries, so much so that even Chatterjee, the Discoverer of protoavis and chief proponent of protoavis theory, doesn't believe in it anymore.
The bird to dinosaur theory is different, it actually suggests the very first saurischian dinosaurs, possibly even the very first dinosaur of any kind, already possessed feather and flight capability. Some descendant lineages of the first flying dinosaurs secondarily lost flight capability and became purely terrestrial dinosaurs we all know. Others kept on flying right through Mesozoic and became modern birds. So bird to dino theory supports a close relationship between birds and Dinos, differing from mainstream theory of bird evolution only in how long dinosaurs went on before evolving flight capability. Mainstream theory says quite a long time, maybe 50 million years. Bird to Dino theory says Dinos had flight capability right from the beginning, but most descendants then lost it.
