GAINESVILLE — Florida delivered its SEC welcome to Texas — back in Gainesville for the first time since 1996 — with a performance the Gators desperately needed. No. 5 UF returned to the win column with an 84-60 victory Saturday after a trying week on and off the court, including a tough loss at home and more turmoil inside Todd Golden’s program. “We came out and we showed that dog mentality,” veteran guard Alijah Martin said.
