Every team has a separate phone line dedicated to Brad. They have a full-time employee whose sole responsibility is to answer the phone when it rings, 24/7 and including holidays.
I would even say that there wasn’t specifically 1 attempt. What you can conclude is that there were Edge guys that were in Brad’s buckets, but they were unattainable via trade or there were better buckets with a non-edge player still in it.
I went to a Cleveland game when Lebron was in the playoffs (many years ago). I asked the scalper: “what do I get for $100?”. They said they’d always take my call. lol. I overpaid.
