If you read the article it wasn’t exactly a ringing endorsement by Simms.
This is what he says about Tua:
“Simms said he believes Tagovailoa can operate this offense at a playoff-caliber level.
“I think he’s the quarterback I thought he would be,” Simms said. “He’s done a good job of acclimating himself to the NFL. I thought that stint at the end of the year [from the Baltimore game on, for the most part] was good by him, good decision making, accurate. A lot of short throws. Many teams that’s what they do, too.
“He gets rid of the football quickly. Throws an extremely catchable ball. He does throw spirals. They did a good job coaching him for what he is.
“I like his body language on the field, his personality. I know players like him. He works hard. With what’s around him, he has a chance to have physical success and apply all that with his personality to the team and get people to galvanize and rally around him.”
Sounds like he thinks Tua can be a good game manager, and that that should be enough for Miami to win a lot of games.
He raves about the rest of the roster though and how well the front office has built it.
