The whole 'interested' thing is stupid. Of course they are interested in all the top guys. Interest doesn't just mean they want to sign him. They need information about the market, they learn about trends in contract structuring, what other teams are doing, etc.
I would not be surprised if Von Miller was their target all along. Jones is talented, but he's not the same kind of leader. Jones is talking about 'the right scheme' which is pretty obvious he doesn't want to drop into coverage. Von Miller is a grit and glue guy.
Von Miller would die before he let 13 seconds happen with him on the field.
