What no one has mentioned in this entire thread is that the Sun have a significant need for a player just like Brooklyn Pope -- a backup 4 who can rebound and score.
Nor did anyone mention that she really was the difference in the UConn - Baylor game this past season. Griner was good, but KML was great in that game (even led BG in blocked shots!!). They basically matched each other's stats. Sims was not a major factor, so almost all the secondary scoring for Baylor came from Pope. As I recall, she had 18 points. At that point in the season, Breanna was not in a position to guard her or match her scoring, and that is the one-sentence explanation for Baylor's victory.
If I were Anne Donovan (or maybe a Sun assistant after having a discussion with her), I would be placing a call right now to Brooklyn Pope. My intention would be to offer her a training-camp contract, depending on how the conversation went. My message would be something like this: "We're interested in your skills, but you need to understand that if you make this team, you will be a backup 4 -- a role player. You need to be prepared to accept (even embrace) that role, or you're going to be gone before you get over the jet lag from the flight to get here. We saw your Facebook posting and we didn't like it one bit. You need to keep that attitude completely zipped up if you're going to succeed here or even stay here."
And if she expresses contriteness, and a willingness to play on those terms, I would follow through and offer her a training camp contract, but she would be on a short leash.
