Yeah, but how often does a team actually do that as you never know when that team you are burning may be the team that could help you out with the key asset you are missing.
I'm not saying it is impossible, I just don't see it as a realistic scenario. Firstly from JPs camp as it doesn't likely get them out of town which they desire. Secondly the other team is burning a bridge for little benefit. Thirdly Edmonton is reasonably positioned to respond, unless someone goes crazy and offers 4M. But even then why would they do that when they could pay him just $1M but offer a slightly better deal to Edmonton. $3M in cap space is quite a valuable asset.
