watched it all. what I saw was "good" not "great". he's being promoted as "great".
Those that are promoting him as great may see him differently than you. Certainly entitled to your opinion, of course.
As pointed out just below your post, however, is that his usage should go up. Many proponents of his would argue that his upside has been limited due to the incredibly poor and low usage in Miami. The good thing about him is that, even if he doesn't look "great" to you, his fantasy points per touch put him near the top of the league. If he's able to maintain that same efficiency, which he has for the last 2 years on a lesser Miami team, then that might explain why he's being promoted as "great".
He's averaged almost 1 fantasy point per touch. If his touches bump up from 240 last year to 300+ this year (250 carries and 50 receptions), then you can see his upside. Considering what's been said about him and the complete lack of a clear #2 RB behind plus the fact that he has the skillset to be a 3 down and goal line back, then 300+ touches for him in Houston isn't a stretch.
Here is a listing of some of the top backs last year and their fantasy scoring per touch. Of note, a guy like Woodhead will never get enough volume despite his crazy efficiency. Some guys don't need good efficiency just because of the sheer volume they get. Either way, Miller's numbers in almost every metric are at least above average. And if he hits 300 touches, then unless he turns into Trent Richardson overnight, then he's a lock for top 5 production. This is why Miller has both a very safe floor AND high upside for this year barring injury.
David Johnson -- 161 touches for 212 pts 1.32
Woodhead -- 188 touches for 244 pts 1.3
Deangelo Williams -- 240 touches for 235 pts .98
Miller -- 241 touches for 234 pts .97
Freeman -- 338 touches for 320 pts .95
Forte -- 262 touches for 216 pts .82
Gurley -- 250 touches for 210 pts .84
Martin -- 321 touches for 242 pts .75
AP -- 357 touches for 266 pts .74
