Time for Vernon Adams, Jr.?

The Niners need a QB who can fit into Chip’s system quickly. I have an idea!

The San Francisco 49ers are suddenly down to two healthy quarterbacks in the middle of training camp, with Thad Lewis’ ACL tear and Colin Kaepernick’s “dead arm” (which is hopefully just comatose, but who knows?).

Suddenly there’s a need for one or two more QBs. Chip Kelly can throw passes in practice, but he can’t absorb hits in the fourth quarter of preseason games when the shakiest offensive lineman are struggling to stop the rush.

Of the available free agents, Mike Vick probably makes the most sense. He won Chip’s first NFL quarterback competition, and could help teach the system to his teammates as well as run…
