Are they talking about the facing stones? If so, this wouldn't solve the main mystery of how they cut and piled the main structural blocks. Of course they had the wheel, but they had to use rollers under the blocks, there not being a wheel that would have lasted even one revolution under a weight of ten tons.
A big log is a wheel, and a bunch of logs would stand under the weight of stone blocks.
