To speak to the first, I'm thinking Scott Milanovich is probably heavily involved and likely Noel Thorpe too. I remember the coverage of Brock Sunderland's first free agency here when they brought in guys like Larry Dean, Don Unamba, and Jovan Santos-Knox and the talk of how Phillip Lolley gave a report on the guys he wanted and shaped the plan. It's likely been a similar process where the coaches have been able to have significant input, especially without the need to game plan much of the past year.
On the second point, you're bang on. I'm sure there's a lot of interest in playing for someone with his credentials.
