To CelticG1, you're right, he could just sign with us. But if he comes here, get's the PT you mentioned, and fits in, he'd have a better shot working something out with us.
Furthermore, we could still sign and trade him (I believe) something we couldn't do if he wasn't on the team in the first place.
To ImShakHeIsShaq, it absolutely is illegal and it absolutely is tampering, but I'm pretty sure people do it. I mean how does the league really stop this from happening?
As long as Kaman's agent represents someone else in the league, how could the league prove Danny was talking to the agent about Kaman? Furthermore, how could the league prove Danny spoke to Kaman or the agent at all? They aren't the government: they can't subpoena phone records.
While I could be wrong about Kaman getting bought out and coming here, I think if it does happen, there's a very good chance Danny spoke to him today or earlier about the possibility.
