Ok, I have kind of a delulu theory, but hear me out - I think Emma Cannon gets waived for Kate by the end of this month.
It's been obvious since, like Kate's second game that she deserves a roster spot. Even though the Sparks are dysfunctional, I don't think they're that blind. Most teams would've already cut someone, brought Kate onto the active roster, and used the open DP spot on whoever got waived. And that's why I don't think the plan was ever to waive one of the rookies or second-year players (Latson, Feagin, or Park), because if that was the move, they would've done it already. It would've kept the roster together, rewarded Kate, and given that younger player a chance to stay with the team in a DP spot. I also don't think they necessarily care about filling the DP spot with someone who hasn't been in their system or with the team since the season started.
Instead, I think they've known from the beginning that Cannon is the odd one out. Since Cannon can't go into a DP spot, the Sparks are just burning through Kate's 12 DP games while keeping Cannon on the roster. Then, once Kate hits the limit, they waive Cannon and give Kate her spot. This has allowed them to basically carry 13 players at no extra cost. And honestly, it might even be a courtesy to Cannon....letting her stay on the roster a little longer and collect a few more game checks before moving on. Am I crazy, or does this actually make some sense?
no that's actually a very good theory haha. guess we'll just have to wait and see!!!
