Left tackle, wide receiver and tight end are among the top needs heading into the off-season. If the Bears can find a starter at one of the spots in free agency then trade the fourth pick to the Chargers for the 12th and 28th picks in the draft that would allow the team to add two starters for the price of one.
GM Jerry Angelo has a history of trading down and the last time he had the fourth pick he sent it to the Jets. The Bears ended up with Michael Haynes and Rex Grossman. Obviously, the grade on that move is still open for debate.
The Chargers were a playoff team and might consider themselves one player away from going to the Super Bowl, so the move makes sense on both ends.
The dream scenario would be if the Bears could sign a quality left tackle, such as Walter Jones and still have enough money to add Jerry Porter. In that case the Bears could keep the fourth pick and take the best player on the board because they're not going to take a tight end that high. Finding a pass catching tight end could then come in the second round.
