The trade deadline sits like an inviting target four weeks away for the Trail Blazers, who have remained in playoff contention despite a recent six-game losing streak. Couldn't they make a deal to improve their unproductive bench and enhance their chances of reaching the postseason? For Portland general manager Neil Olshey, it remains a question laden with risk. The Blazers may be able to come up with a short-term deal to increase their production. But that same deal may also damage the long-term goals of a young roster and ruin a formula that has been succeeding beyond anyone's expectations.
