There might be more teams interested, or it could all just be to try and build leverage to get a deal done with denver.
The San Francisco 49ers are trying to figure out a trade for Colin Kaepernick, and NFL Network reporter Mike Silver thinks it is close to happening. Earlier today he said the Denver Broncos were pushing hard, but now he is saying two other teams are involved in discussions. Ian Rapoport said he is hearing the same thing.
It is possible there are other teams interested, and it is possible the 49ers are pushing this out there to force the Broncos into a deal.
