You mean like he knew what Haywood would be offered? Nobody knows for sure, but it's not hard to find a list of FAs and compare it to the amount of teams who will have money. As of now I believe there are about 5-6 teams that will have enough money to make an offer. There could be several more that can clear some cap, but Hood is nowhere close to the top of the FA class.
DL is not looking to dump Hood because he's worried about a big offer. The FA landscape this year is night and day different than it was with Kanter. If that was the case, DL would have tried to dump Hood a lot sooner.
Look around the league and it's easy to find players who misread the changing FA money available. Hill, Noel, etc. lost out on a lot of money because things have changed drastically from where they were a year ago. The main reason being because the salary cap came in 9 million lower than expected.
Anyway, as I like to say, hide and watch. DL may be shopping Hood, but it's not because he's desperate to dump him like he was with kanter.
