Pretty decent video compilation of his week 2 runs
here.
I'm more impressed with his power/tackle breaking in that video than I am by his speed or moves. His speed frankly looks like "RB average", and I didn't see any moves, just runs that were pure sweeps or off-tackle. No jukes, no cuts.
Like I said, it's a good thing that he was breaking through arm tackles with ease, but that's also in the second half against guys who mostly won't be in the league, and certainly won't be starting, in just a few weeks.
For me, the jury's still out, but I'm not counting on him to produce this year and I have my doubts about his value long term. And for the record, I drafted him late in one dynasty league and am rooting for him, but that's just the way I see it.
To finish this thought, take a look at
video of Ladell Betts from his week 1 preseason game vs. the Bills. Betts is talented but nobody special, and is only arguably even starting material in the NFL. He's a high quality RB2 by today's NFL standards. In his short video, he shows burst, juke moves, cut backs, and power running. That's what a rosterable running back looks like, not the guy who put together the "nice" runs that Forsett did in his video from yesterday.
