Jimmy Garoppolo's only started five games for the 49ers, but that's all Ron Jaworski's needed to see -- 'cause he's telling TMZ Sports the S.F. QB "absolutely" can be a Hall of Famer!!
"When I see a Garoppolo," Jaws says, "I see a guy that the sky is the limit."
The ex-Eagles QB tells us he loves the way Jimmy plays with his mind, arm and legs ... and says he's basically a cross between TWO Niners legends.
"You've got a Joe Montana, Steve Young kind of guy in San Francisco right now, and that's going to be the pillar of that football team for a good decade," Jaworski says.
