"I truly believe Colin Kaepernick could be one of the greatest quarterbacks ever," Ron Jaworski said Wednesday on ESPN. "I love his skill set. I think the sky's the limit."
Kaepernick was asked how he handles such lofty projections.
"I'm working," he responded. "To me, it's a great honor he said that. I'm very flattered by it. But at the same time, I haven't played a full season yet."
Kaepernick took over as the 49ers starting quarterback after Alex Smith was injured last season and led San Francisco to the Super Bowl.
He emerged as one of the NFL's most potent dual-threat quarterbacks, throwing for 1,814 yards and 10 touchdowns in seven regular-season games and rushing for 415 yards and five touchdowns.
He threw four touchdown passes in three postseason games and rushed for 181 yards in the NFC division playoffs against Green Bay, setting the single-game NFL playoff rushing record for a quarterback.
The 49ers are considered a Super Bowl contender this season and Kaepernick, after just 10 NFL starts, is one of the league's biggest stars.
Kaepernick also appears on the cover of the latest GQ magazine.
