Not everyone will. People still have trouble accepting that we traded Jarrett Jack for Robin Lopez.
Correct. Most people just don't pay enough attention, which is fine. The issue is when people think they know and just have no clue.
There is also the issue of these posters who think constant complaining is contributing. What they don't realize is that problems are much easier to spot than solutions. By only pointing out problems and never a real solution, they show their true ability.
As far as going from a Room team to a tax team . . . you can cover the ~$13m gap in one trade after chewing up the Room MLE and adding a min player, then you send out ~$20m. This is rare, but it's quite possible. It's easier to do in a series of trades to get you there.
Or just a trade sending out $26m and getting back $39. Then sign min players to put you over.
It's practicality stopping you. This would really only be a good idea to get stars, but how with so little going out, or to dump long-term salary for expiring to blow it up.
