You may be right. But at her age and salary level, I’m not sure many WNBA teams are willing to make a financial commitment to DT, including Phoenix. On the other hand, an expansion team like SF is going to have a few rookies and essentially several castoffs from other teams. The Valkyrie will not win a championship next season. So the possibility of signing DT as a way to boost ticket sales and interest is something to think about.
Of course all this depends on whether or not DT wants to continue playing, and if so, for a team other than Phoenix, assuming Phoenix decides to move on. Time will tell.
