I don't see anyone agreeing with this very, very bold statement...
Let's remind everyone about a few facts :
1. Isner is in fact, a dangerous player. He is in fact much more than a serve. He is a high octane player, and when he is on, he is essentially unplayable.
2. Isner is at a career high singles rank of 28, even higher than his other fellow giant Ivo Karlovic.
3. Isner just won his first ATP title ever, and is riding high on confidence.
4. Andy Murray last year finished in the 4th round of the Australian Open, and the 4th Round at the USO. He lost to Verdasco, and Marian Cilic. Guess what? They both serve big and hit big. Sounds like some big giant fellow I know.
5. Andy Murray has a tendency to play passive, especially in the early rounds of a slam. In fact, he sometimes just plays outright terrible in the early rounds. Isner if he plays to his seeding is meeting Murray in the 3rd round I believe (if I looked at the draw right).
Are you going to tell me these facts are wrong? Is it so bold to think that the 28 seed could actually beat the 4 seed? *Gasp*.
