TAMPA — We’ve reached that point in the offseason where the acquisitions are mostly done. Coaches, receivers, cornerbacks and the rest have all been introduced to the bay area in the past four months.The only thing left to add is imagination and trust.And just so you know, those last two are up to you.Tell me, are they in short supply?Because it’s not as if the Buccaneers haven’t tried. They’ve brought in a whole new coaching staff and revamped the defense with spare parts and college players. Tampa Bay will definitely look like a new team in 2019.But will it be a much better team?Looking objectively at the roster, it’s hard to make a case that the talent level has dramatically increased. You gain a potential star in linebacker Devin White, but you lose Kwon Alexander to free agency. You gain a potential deep threat in receiver Breshad Perriman, but you lose Adam Humphries and DeSean Jackson. You add a small bushel of defensive backs in the draft, but there’s not a sure bet among them. You’ve done little on the defensive line except put another candle on Jason Pierre-Paul’s birthday cake and mull waving goodbye to Gerald McCoy.The problem is not the choices made this offseason but the commitments made in previous years. Tampa Bay’s salary cap was stretched so thin there was no room to maneuver for 2019.Virtually every team in the league made some kind of major move to upgrade during free agency. Tampa Bay’s two biggest acquisitions were Perriman and linebacker Shaq Barrett, who both got one-year, $4 million contracts. For comparison’s sake, there were about 60 free agents who got larger deals.That means the greatest hope for change will not be in personnel but in coaching and schemes.And that’s where the trust and imagination come in.If you believe the Bucs were seriously underperforming for previous coach Dirk Koetter, then maybe you see reason for optimism. If you believe coach Bruce Arians and defensive coordinator Todd Bowles can replicate the turnaround they once performed in Arizona, then maybe you see a postseason run in the near future.But that takes a lot of trust.That means Arians has got to find a running game where there was none last season. That means he has to eliminate many of the mistakes by quarterback Jameis Winston, who has the highest interception rate of any full-time starting quarterback since 2015.The means Bowles has got to create a pass rush with his new 3-4 defense, utilizing White, Barrett and another bargain free agent acquisition in linebacker Deone Bucannon. And that means Bowles has to get a lot of young defensive backs up to speed in a hurry.Those are not impossible tasks, but it suggests an awful lot has to go right for the Bucs to be playoff contenders by the end of the year.What are the odds?It usually happens once or twice every season that a team coming off a 4-12 or 5-11 record makes the playoffs. There were actually three that did it last year: Chicago, Houston and Indianapolis.So, no, it’s not out of the question.But the margin of error is small.Of course, you already know that. You’ve already endured one of the longest postseason droughts of any fan base since the NFL went to an expanded playoff system in 1990.The Bucs have been signing, trading and drafting players every spring during the past decade and very little has changed. Four different head coaches have come and gone, and not a single one has gotten Tampa Bay into the playoffs.Are the Bucs any closer to the playoffs today than they were after the final regular-season game in late December? Yes, I think they are.I’m just not sure they’re close enough. Contact John Romano at firstname.lastname@example.org . Follow at @romano_tbtimes.
