McGonagall spent hours spying on the Dursley’s and didn’t want Harry to be put in their care

she bought him a Nimbus 2000 with her own money and since it was new at the time, it must’ve cost a lot

she put Harry on the quidditch team without checking with Oliver Wood and if it had been another student who was caught flying, they would have been expelled on the spot

she defended Harry in front of Umbridge “He has achieved high marks in all Defence Against the Dark Arts tests set by a competent teacher”

“Potter. I will assist you to become an Auror if it is the last thing I do! If I have to coach you nightly I will make sure you achieve the required results!”

when Amycus spat at McGonagall, Harry cast the cruciatus curse on him which worked meaning Harry truly meant it, and when McGonagall called him foolish, Harry replied as if his actions didn’t need explanation 

“The scream was the more terrible because he had never expected or dreamed that Professor McGonagall could make such a sound” when McGonagall thought Harry was dead
