Aden Baldwin had given Notts the lead in the first half.
But the visitors responded through McEntee's double to seal the points for a happy boss.
"We are a good team, a very good team playing against what I also think is a very good team too with the way (Williams) Luke plays and the way he sets the team up," Sadler said.
"They are a very and good team, they take teams here, but we apart showed what a fantastic team we are and by team, I mean everybody together.
"The first half we go in 1-0 down, but I said to the lads that I thought we controlled the game out of possession, the only thing missing in the first half was just that final piece of quality at times.
"But I knew we could hurt them as the game went on and the lads believed we could hurt them as the game went on.
"I gave the players a few minutes to speak to themselves, I always do. You get a vibe from what they are saying but, in the end, we got what we deserved."
