​The Indiana Fever are in a unique spot — nay, predicament — as Sunday’s WNBA trade deadline approaches. They are playing their best basketball of the season. Tuesday’s win over the Seattle Storm pushed their record to 18-10, good for 5th in the standings, and will look to extend their season-long four-game win streak this weekend at Portland (Friday) and Minnesota (Sunday). The Fever are a virtual lock for the playoffs, and with a historically good offense headlined by All-Stars Caitlin Clark, Kelsey Mitchell and Aliyah Boston, they look the part of a potential title contender.That being said, this team has needs. Needs that could be addressed ahead of the trade deadline.Monique Billings and Makayla Timpson have both been trending up in recent weeks, but with Boston still battling a nagging lower right leg injury and the seldom-used Damiris Dantas currently unavailable, the frontcourt would benefit from the addition of another true post player.Wing is also rather thin with no one really beyond Sophie Cunningham off the bench and Lexie Hull, who has struggled with offensive consistency all season. (Yes, in theory, Justine Pissott could have filled this role, though it would have required a roster move to keep her from the Aces.)But here’s the rub: WNBA rosters are limited to 12 players (six protected) and the Fever have $6,655 in available cap space, meaning any player exchange would have to involve lesser or matching salaries. Acquiring Napheesa Collier, for instance, would require moving half the roster.Indiana also faces a dearth of trade chips.Clark, Boston and Mitchell are untouchable. Full stop. Move on.Timpson (under contract through 2028) likely falls into that category, too, as does Hull, who carries a $765,000 cap hit ($803,250 next season).The Fever have a surplus at guard, but veteran Tyasha Harris is on an expiring deal and rookie Raven Johnson is cheap and under contract for the next two seasons (club option for 2029). The former likely wouldn’t net a worthwhile return; moving the latter makes little sense unless a suitor is willing to overpay.What about Billings? With how she’s played recently, the 6-4 veteran forward — who still has another season on her contract — could fit with a team looking to add an experienced big … but what would the return be for the Fever? If not a top-6 caliber forward, then what’s the point in subtracting from the frontcourt?The most intriguing trade chip: Sophie Cunningham. She’s on an expiring contract and in the midst of a phenomenal season, averaging 9.4 points on 47.5% shooting (44% 3FG) off the bench. Though the 6-1 wing would likely net a decent return, she is the Fever’s most-reliable scorer beyond the top three.Fever coach Stephanie White deferred to general manager Amber Cox when asked Tuesday if she expected the organization to be active at this year’s deadline. But considering the current constraints, it appears unlikely Indiana will be involved with any significant moves — unle
