In fact, Tannehill had the best day of any Dolphins quarterback when it comes to throwing the ball. Bar none.
Tannehill showed off his strong arm throughout the 2 1/2-hour practice and practically every one of his passes was right on the money.
Sure, Tannehill was picked off twice during the practice, but both came after his receiver tipped the ball to a defender. In other words, those weren't on him.
Offensive coordinator Mike Sherman said afterward he was surprised by how good Tannehill looked given the fact he had missed the first two days of camp.
Before we go overboard, let's point out that Tannehill did go against the second-team defense all practice. That was done with the idea of helping him catch up, as he got more reps than any other quarterback.
Sherman indicated after the practice that Tannehill would soon start getting reps with the first-team offense.
In terms of arm strength and zip on the ball, it's clear that Tannehill is the best of the three, and he's also probably the best athlete of the group.
What he needs to show is the ability to make quick decisions, something that was an issue in the spring. Sherman said Tannehill has gotten better at that, but it remains a work in progress.
Tannehill, in general, remains a work in progress despite his impressive showing on Sunday.
There will be days when he doesn't look good and other times when he's dazzling. The test for him will be establishing some sort of consistency.
Because of their experience, Garrard and Moore both would seem to have a clear edge over Tannehill in the battle for the starting quarerback job.
But if Tannehill has many more days throwing the ball like the one he had Sunday, he just might be starting right away.
