I think the Sun must be a tough team to play for this year - previous years, not so much. I think they have made some questionable trades and personnel moves over the years but this year it is really down to injuries - they have been ravaged. Not sure about the new coach, and wasn't all that sure of the previous one - players liked him, but the games I watched where the Sun were competitive but ended up losing, he seemed to sit starters too long and let the other team gain momentum. And a few of his personnel moves really stumped me.
For Tina ... would be sad to see her go and would be devastating for the team. But I could see her wanting a new start somewhere. She has really struggled this year with opponents able to focus defensively on her.
It is a little weird in the WNBA - free agency isn't 'all about the money' as none of these players can earn much. It really comes down to teams trying too woo players.
The other downer for the Sun is while beautiful country Eastern CT is not exactly hopping. New London and Providence I guess are the nearest cities and they aren't all that exciting either. Tina having grown up in NYC may find it just too quiet! I know Storrs is sleepy, but that was college, finite and with a built in pool of 20,000 age mates.
