"Here comes this hulking young man walking across the field," said Mike Kelly, who does radio play-by-play for Missouri football games. "You could just see heads start to turn as he walked — ‘Who is this guy?’" [...]

Kelly took one look at Smith’s technique and christened him Godzilla. Some of the 49ers call him Cowboy now — Smith is built like a bull and about as down to earth, too — but Godzilla still seems more apt. There is little artistry about Smith’s game, none of the swim moves and spins that might free smaller players. That is not necessary for Smith.

"Just brute force," Kelly said. "Like all of these skyscrapers, just knocking them down."
