I can see 3 or 4 teams who might take Kaepernick, but not for this year. He might net an invitation to camp for next season if these workouts went well. That’ll give the team time to smooth the roiling waters that will result from the signing announcement.
The teams that will touch him....will ones who simply want a back-up quarterback for a very cheap price. That was the problem from two years ago...I think of the NFL teams was willing offer up a contract but it was the back-up guy. I would also suggest that the teams in the running are all from the bottom ten teams in the league, with nothing much to lose.
