Making a trade doesn't mean you have trade flexibility. Of course you CAN trade, you just don't have as many options and as much of a market without cap space, which is important for a team that doesn't project to be a contender.
So the plan is to use the 1st rounders to dump those contracts he signed? He signed bad deals, and now they are in a bad spot because of it. His plan was for the contracts to work out and/or be tradeable.
No, but he can if that is what the owner wants. If the owner doesnt care about footing a bill then have a lot of draft picks in a good draft. I dont think they need to sign anyone to become a better team. They have a lot of room for improvement just within the team.
