It really is this simple. When Donovan is on then they need to make every effort to go to him. No need for Solomon shooting 3's or Wiggs trying to shoot a contested 15 footer. Or Jakolby Long shooting a 3. Just drive and kick until he misses 2 or 3 in a row. He is an elite shooter and when he is feeling it they need to keep going to that well.
As for defense....they simply have no chance. Lard can't defend s stretch 4 (yet). Solomon doesn't have the foot speed to recover to the corners after helping on the pick and rolls. The adjustment should have been just having Wiggs go under every screen until Alex Robinson shows the ability to hit a 17 footer.
I was going to write this exact thing. I will add that the problem I saw in the pick 'n roll was Brase was coming up too high in the paint to guard Robinson, even when Wigginton went under the screen. So now both Wigginton and Brase are defending Robinson, vacating the paint for Brodziansky. And it happened over and over. And over.
Some people are blaming Solomon's foot speed for giving up all those three-pointers, but to me it has more to do with him and the other forwards giving their man so much room because they're not comfortable guarding the perimeter. For one of those open threes, Brase was standing almost in the paint and his man was at the three point line in the corner when he received the ball. You can't cover that much ground no matter how quick your feet are.
We have a couple good shooters on this team in Wig and Jackson, and a big man in Lard who can handle himself inside. Overall, this team has pretty decent shot selection, but those three guys plus Babb should be taking the lion's share of our attempts. Babb is probably the best at driving to the rim. Jackson really struggles with that, and Wig struggled with it a bit yesterday. He tends to force it a bit too much.
As far as fixing these problems ... the offensive missteps seem easier to fix than the defensive ones, because our offense is actually not that bad. We do some things better than in year's past, like offensive rebounding.
The defensive struggles will be harder to fix, partly because we don't have the personnel. I'd like to experiment with Talley at the 4 because I think he can cover those stretch-fours and fives who've been burning us from outside this year.
