If this trade goes through, the Dallas Mavericks would simply replace Andrew Bogut with Greg Monroe at center. Bogut and Monroe bring different things to a team, but they are arguably pretty comparable players overall. Monroe is a more effective offensive player in the post and is more of a scoring threat than Bogut. However, Bogut is considered to be one of the best defensive centers in basketball, while Monroe is looked upon as a rather weak defensive player, per ESPN NBA Real Plus-Minus statistics.
Monroe is younger by six years, but he also has two years and $35 million left on his current contract; Bogut is in the final year of his contract (at a more affordable $11 million per season). Greg Monroe is capable of playing power forward, and with superstar Dirk Nowitzki nearing retirement, Monroe could be a potential long-term replacement if the Mavericks chose to go that route. Devin Harris was once a very good player, but he is on the decline and is essentially a throw-in to make the salary cap numbers work — and this would be a legal trade under NBA rules, as confirmed by the ESPN NBA Trade Machine.
The Milwaukee Bucks would be likely to agree to this theoretical offer, in part, because they are having a difficult time moving Greg Monroe and his bloated contract. The team could reacquire Andrew Bogut, who spent the first six years of his NBA career in Milwaukee, and see how well he fits with the current roster and style of play. Alternately, since Bogut’s deal expires after this season, the Bucks could use that money to entice a quality free agent to join them next summer if they choose to let Bogut walk at the end of the year. Either way, this deal would give Milwaukee some options and flexibility that they don’t have as long as they hold onto Greg Monroe.
