If I was in Dontari Poe's position where there is strong demand from multiple teams, I would want to visit each team, meet the Head Coaches, position coaches, GMs, etc. Each team knows from his agent what sort of remuneration he is hoping for and there are other considerations like taxes, etc to consider. I don't think that it's as simple as who offers the most money. Another key consideration is understanding what defensive system will apply and does he fit well in that system. Are there any issues associated with each team. Eg Tom Coughlin is now the top guy in Jax. He has cleaned out a lot of the players and is starting afresh. He will probably insist on the team being tightly disciplined, etc.. Atlanta had a good team last season but choked in the last quarter. It may be difficult for the team to psychologically overcome a choking performance like that.
While we as fans want an immediate decision, I respect the player's right to evaluate carefully all the strengths and weaknesses of each alternative team and sleep on it before making a decision.
Poe probably has a wife/partner and may want to discuss it with her. I can recall the story of a top O-lineman we were wanting to sign and the Dolphin GM of the day drove him around the beautiful beaches, but his wife was very religious and unimpressed by scantily clad beautiful bodies. He liked Miami but signed with Chicago for a little less because his wife called the shots.
I expect that we still have a decent shot. 9 hours of meetings in Miami sounds a pretty long time. If it wasn't a decent fit that time would have been condensed. It's also significant that Ndamukong Suh, Andre Branch and coach Adam Gase share the same player agent, Jimmy Sexton as Dontari Poe.
