Physically Frazier is closer to Tyson. They were also good fighters on the swarm, Frazier was busier on the inside, Tyson more powerful and intimidating. Look at how Foreman's height, reach, and power neutralizes it pretty decently.
Heck old George could've put on a decent show too, against a Don King era Tyson. He had a good showing against a prime Holyfield, and Holyfield gave Tyson problems.
