No. 15 Wisconsin had seized momentum at the Breslin Center, early on in the first half. The Badgers held a 12-8 lead over No. 7 Michigan State with 9:23 left in the first period, after answering an early Spartan run.
Green scored 22 points Thursday night.
From there, it was all Spartans, as Michigan State used a 23-7 run to close the half, and outscored the Badgers 61-43 the rest of the way, cruising to a 69-55 victory.
"That run hurt us," Wisconsin Head Coach Bo Ryan said. "They got a couple baskets in transition, guys thought they were back but we weren’t.
"Turnover, long rebound, that’s not a position we normally put ourselves in. That’s why we try not to turn the ball over.
"Then right after that we’re playing from behind. Our guys have some fight but when you get in that big a hole it’s tough.”
Junior Forward Ryan Evans led Wisconsin with 17 points and six rebounds, but was about the only thing the Badgers had going offensively.
Wisconsin just shot 34.6 percent from the field (18-52) and 20.8 percent from beyond the arc (5-24).
Senior Guard Jordan Taylor was held in check most of the night. Taylor managed 13 points on 3-13 shooting.
"I thought if he could have hit a couple shots early, especially when you go on the road like he has in some other games, just get something going early," said Ryan.
Evans led Wisconsin with 17 points.
"I thought he did a good job at penetrating and finding people in the second half. I know he ended up with five assists but in a game like that, five assists seems like 10. …
"He struggled with his shot, no question about it, and he’s had a couple of those. But he keeps fighting, he keeps driving, he led that comeback.
"So, we’re not trading him.”
Appling finished with 20 points and four assists, while Green led the Spartans with yet another double-double. Green had 20 points with 10 rebounds and shot 5-9 from the field.
"I enjoy watching him play every minute," Michigan State Head Coach Tom Izzo said of Green. "He got tired tonight and had a couple let downs, but he has just grown up so much.
"He is learning how to do a better job, and for a guy that only got nine shots he did a lot of damage with everything he does.
"Appling creates a lot, we had a good one man break with him. ... When (MSU's bigs) run it clears out for Appling and he is as quick a guard as I have ever had."
