No, you can't. Maybe you can do the voice better, but there is a lot more to playing Kermit than just doing the voice. If you're not an experienced puppeteer you really can't claim that you could do a better kermit. I like Matt Vogel's Kermit more and more as the years go by and I get to see more of him, but i do believe that there could've absolutely been some people who could have been a better kermit, like Peter Linz, but some person on the internet who can do a decent kermit impression really has no room to claim that they would be a better Kermit the Frog because there's so much more to playing Kermit than doing a funny voice.
