As Dana Brown works through the final year of his current contract as Astros general manager, its fair to start evaluating his tenure the same way you would any executive in professional sports.Create a ledger.Put the good decisions on one side, the questionable ones on the other, and determine whether the positives outweigh the negatives.There have certainly been positives.Perhaps Browns biggest success came when the Astros realized they werent going to sign Kyle Tucker to the massive long-term contract he was eventually going to command. Rather than allowing another star player to simply walk out the door, Brown acted.The Astros traded Tucker and received Isaac Paredes, Cam Smith and Hayden Wesneski in return.Whatever you think about losing a player of Tuckers caliber, Brown deserves credit for recognizing the situation and maximizing the return while he still could. Paredes has become an important piece, Smith has enormous upside, and Wesneski gave the organization another young arm with potential.Put that one firmly in the win column.Unfortunately, the other side of Browns ledger has become increasingly concerning.After the Astros allowed Framber Valdez to leave in free agency, Brown suddenly had money available to reshape the pitching staff. Houston brought in six pitchers for the 2026 season.Three have already been designated for assignment.Thats not exactly a ringing endorsement of the organizations offseason evaluation process.Then theres Tatsuya Imai.At roughly $19 million per season, Imai was supposed to help stabilize the rotation after Valdezs departure. Instead, his first season in Houston has been an absolute roller coaster.Between adjusting to Major League Baseball, adapting to a new country and dealing with the cultural challenges that come with pitching in the United States, the transition clearly hasnt been easy. But eventually, baseball becomes about production.Imai has been erratic and largely ineffective, and now hes pitching out of the bullpen.That creates an even bigger question for the organization: What exactly is the return on that investment going to look like over the remaining years of his contract?Its one thing to miss on a short-term acquisition. Its another when youre talking about significant money committed for multiple seasons.Then theres Mauricio Dubn.For several years, Dubn was one of the most valuable complementary players on the Astros roster. He could play virtually anywhere on the field, gave the team a professional at-bat, provided Gold Glove-caliber defense and was exactly the kind of versatile player championship teams need.Yet Houston moved him, in part because of concerns about his salary and the flexibility the Astros believed they needed to add elsewhere.Fast-forward to today.The Astros reportedly have approximately $9 million in financial flexibility remaining, while Dubns roughly $6 million salary would have fit comfortably within that number.Considering how inconsistent Houstons offense has been and how frequently the Astros have searched for answers at multiple positions, wouldnt Dubn look pretty good on this roster right now?That brings us to the trade deadline.For a team that fought its way back from a terrible start and put itself in position to contend for another division championship, the deadline was underwhelming.The Astros did acquire center fielder Daulton Varsho, but the price was significant: Spencer Arrighetti, a starting pitcher with three additional years of team control.Meanwhile, Varsho can become a free agent after the season.Maybe the gamble works.Maybe Varsho rediscovers the player he was a year ago, becomes a difference-maker down the stretch and helps Houston make another deep postseason run. Maybe he enjoys Houston enough to re-sign and becomes part of the teams future.If those things happen, the trade will look considerably better.But thats a lot of maybes.Right now, Houston surrendered years of control over a starting pitcher for a player who could potentially be gone in a matter of months.Thats not a sure thing.Thats a gamble.And when you combine that decision with some of Browns other recent moves, its fair to wonder whether a general manager working without a contract beyond this season is beginning to feel the pressure.If Brown truly is fighting to keep his job, then he shouldnt be finished.The trade deadline may have passed, but other opportunities have emerged.Marcell Ozuna, Jorge Soler and Austin Hays are among the veteran bats who could potentially provide more offensive upside than some of the options Houston continues to run into its lineup.Are any of them perfect solutions?No.But were well beyond searching for perfect.Were searching for better.If Houston can add a veteran hitter without sacrificing another prospect or young pitcher, why wouldnt Brown investigate every possible avenue? Wheter his future is yet to be decided or already sealed, finish the job by finishing the year strong. Go for it! Its in everyones best interest, even Browns, even if its not in Houston next season. This team deseves every opportunity to make a run and finish the season strong.As always, Astros fans, I want to hear from you.How do you evaluate the job Dana Brown has done? Have the good moves outweighed the bad ones? And with the trade deadline behind us, what, if anything, should he still do to give this team its best chance to win before its too late? Can he save his job?
