Niners Nation pointed out that coach Jim Harbaugh likes his big backs to throw some bone-crushing blocks when they're in the backfield. Last year, Isaac Sopoaga answered that call for the 49ers most often.
But in the last preseason game, it was second-year, 6'4, 293-pound Will Tukuafu who showed why he got a lot of preseason playing time with a couple of huge blocks against the San Diego Chargers.
Tukuafu may be playing himself into the fullback conversation, which is great for the youngster, who hasn't seen a lot of minutes at defense. It would also allow Harbaugh to potentially use Sopoaga in a different fashion -- and having too many big bodies on a team can never be a bad thing in the NFL.
