Yep, those are two great reasons. Here are some others:
1.) Came up with the "windmill" method of playing.
2.) Came up with idea of smashing his guitar from the influence of this artist who talks about destruction.
3.) Brilliant song writer.
4.) Made synthesizers popular in rock and showed how awesome they are.
5.) Basically invented the rock opera with "Tommy", along with writing other rock operas that ruled as well.
6.) Excellent guitarist and definitely one of the more influential ones.
7.) Puts on an incredible live performance showing that The Who just isn't great in the studio, but possibly even better outside.
8.) His fingers bleed with pain sometimes when doing the windmill and yet he still goes on doing them faster than ever and forgets the tough pain
.
I think it might be possible to say that Pete has done more for rock n' roll genre of music than anyone else and it's not just Pete but everyone in The Who had an important role. Daltry had very strong vocals for rock, gave a great image to the band, and his yell in "Won't Get Fooled Again" made history. Entwistle showed that the bass can be an independent instrument and doesn't have to follow another; some people even call him the Jimmy Hendrix of the bass guitar. And then there is krazy old Moon who was a wild man on drums pounding them away like no one had ever heard before back then and was the humerous side of the band who everyone loved. Each band member did their job outstandingly and were the best of their kind for their time it seemed. Their live performances especially show how amazing they can be.
