Jury is still out on Tannehill but he "looks" better than Henne.
He looks better than Henne did the past two seasons, but not necessarily better than Henne did in his first 8 starts.
Henne never moved around inside the pocket like Ryan or made some of the touch throws Tannehill has made.
We were 7-3 in Henne's first 10 starts though, with an extremely comparible supporting cast.
Only time will tell. But Tannehill clearly has more physical talent, (athleticism, touch), and seems to handle the mental part of the game better, (pre-snap responsibilities, doesn't stare down his WR's nearly as much, goes through progressions better, more calm under pressure, etc.).
One other thing is the week-to-week development. Tannehill is a much better QB than he was 1 month ago, and a month ago was better than the previous month. For the most part, (taking out that great game against the Jets), Henne was Henne from start 1 through 10.
Plus, this is all while Tannehill had half the college starts, and we're comparing his rookie year to Henne's 2nd season.
