With Katie, I think what you are seeing is one the main reasons her shot is so woeful right now (and her turnovers are up). Five plus games ago the screener's defender wasn't as consistent in double-teaming right away and when it did she was taking that shot immediately, before the defense could recover. Now teams scouting reports probably report exactly what you saw tonight Bill and the Fever/Katie have yet to adjust.
I also think Tamika was screening for Katie more during her hot shooting streak and I am not sure why that has changed - when Catch rolled to the basket she forced the defender to go with her so Katie couldn't get doubled.
Interesting that Zellous was benched - I hope it was because of her shot selection and that we'll see a little bit more aggressive version of her when she gets worked back into the rotation. Honestly, she reminds me a bit of Brandon Rush - good defensive player, and plenty of under utilized offense talent. :/
Nice to get a win, good to see much better transition D - but I wish Dunn had a talented. offensive minded coach to help her out in that area.
