Per Michael Rosenberg of The MMQB, Kelly believes Kaepernick has what it takes to play for a playoff-caliber team again.
"Do I think he is one of the top 64 quarterbacks in the world? There is no question," Kelly said. "Does he have the ability to play quarterback on a winning team in the NFL? There is no question."
Kaepernick became a free agent after opting out of the final year of his contract with the 49ers. The 29-year-old bounced back from an injury-shortened 2015 by throwing 16 touchdowns and four interceptions in just 11 games as the starter last season.
This is Kaepernick's first time as a free agent in the NFL. He's still young enough to search for a starting job in the league but will have to prove himself to a new set of coaches that he can win games after going a combined 3-16 over the past two seasons.
