​In the history of basketball, we have certainly seen some why-would-they-do-that? pairings.Jerseys and sleeves. Kawhi Leonard and a tree sponsorship. Utah and “the Jazz.” Once, there was even Detlef Schrempf and a headband, if you can believe that.Ja Morant and Damian Lillard?We’re about to find out if they belong on such a list.Because of all the things you might have said the Trail Blazers needed as they prepared to welcome Lillard back after making a playoff run without him, a slight-of-stature ball-dominant guard with a questionable jump shot would not have topped anyone’s list.Depth on the wing? Yes. Shooting? Definitely. Defense? Always.Morant doesn’t particularly address any of those, and yet, he’s here, a dynamic two-time All-Star in need of a second act, being paid a team-high $42.1 million to play the same position as not just Lillard, but Jrue Holiday and Scoot Henderson.Heck, the Blazers’ most valuable point guard last season was forward Deni Avdija.“I’m sure there will be questions about fit,” General Manager Joe Cronin said Monday.Uh, yeah.The Blazers have little more than three weeks before the regular season begins in which to figure that out. At the team’s annual media day on Monday, Morant appeared in a fresh white No. 1 Trail Blazers jersey. It’s happening.“It’s easy for people to be like, ‘Man how is this going to work,’” Lillard offered. “‘They can’t do this, they can’t do that.’ But being on the floor with them … we can be a dangerous team and I really believe that.”The onus is on the Trail Blazers starting this month to prove that they bet right in acquiring Morant. And that pairing him with Lillard isn’t the boondoggle conventional wisdom suggests it will be.Lillard noted how many teams that succeeded in the playoffs last year, think San Antonio with its four point guards, relied on numerous playmakers. To his credit, Morant said he would be comfortable coming off the bench, if necessary.But they would not be the first NBA team to fall into the trap of believing they are capable of adjusting or that they will be comfortable sacrificing. It isn’t uncommon to see players in those situations default to familiar habits and sensibilities once the season is underway or struggles come.That’s what made a lot of the positive energy around what sure seems like an awkward roster ring so hollow. We’re going to need to see it to believe it.Morant tried to lay out a vision for how it could look. If he drives to the paint and is double-teamed, someone else is inevitably open. That’s how basketball works.“That allows me to have more space to be the best Ja I can be,” Morant said.The 36-year-old Holiday, who would be a more natural complement next to Lillard or Morant than they are to each other, made his own case for why the point guard rotation makes sense.“It’s about being a complete basketball player for myself,” he said, “and I think we have a lot of guys like that.
