Take it with a grain of salt, but speaking to one of my Bulls sources, I've heard the team is unlikely to exit this Thursday's draft with whomever is drafted at 28 and 30. They're investigating multiple trade scenarios (trading up, trading for Courtney Lee, or taking on salary for a higher quality player (no details there, but I would guess Iguodala, Gordon, Ellis, and Martin are the guys whom this at least sort of fits).
I'm not sure I make much of the rumors, through five or six years of having sources around the league that hear this scuttlebutt I've been told by a GM that the Bulls completed the Amare Stoudemire trade, that LeBron was definitely coming to Chicago, and a bunch of other things that never happened.
At this time of year, there's little reason to believe in rumors, because everyone is motivated to spread disinformation in order to attempt to get leverage.
That said, this particular rumor makes a lot of sense to me. I've never expected the Bulls to keep both picks as they really don't have the minutes to develop two guys. If they did keep both picks, I would expect one of them to be a Euro prospect who's going to stay in Europe for a season or two. However, I'm not sure if there are any Euro prospects available that are worth drafting around our selection.
Courtney Lee, if it goes down, would be a very nice incremental improvement for the team. He wouldn't radically change what we have, but would give us another strong wing defender, except one who can shoot and put the ball on the floor at least a little bit.
Is Lee enough to put us over the top? Well Lee isn't good enough to swing three games in a playoff series IMO, however, if you work under the theory that the Bulls overall played poorly and that they were close, then Lee could provide the incremental improvement to help the team considerably if Rose/Noah/Boozer have a better series.
