I thought they might even keep two kickers, but roster spots are very tight.
Looking at the kicks he made in the first game, I was all over Nordin. What was great was not just the distance but that his kicks were so straight: not great big bananas. He looked like a young Gost.
Then I watched and re-watched Nordin's kicks from the second game, but it's very hard to tell much unless you see him up close and repeatedly to see what he does different from kick to kick. Still, for what it's worth, he seemed to be leaning left and have his plant foot too far from the ball. That would make you push your kick, which is what he did.
There was a story that he didn't have a precisely measured run-up when he was at Michigan. That isn't as terrible as you might think. The three things that really, really matter are your plant foot, your swing and (for the NFL) timing. If you can get your plant foot where you want it when you want it, everything else should sort itself.
So, unless he has mental problems, I think he should be fixable. What concerns me is whether the Patriots have anyone who is a competent kicking coach to fix him. Kicking is completely different from all of the other skills that football ("foot"-ball) players need. Knowing how to teach one set doesn't help you teaching the other. And kicking is individual: like a golf swing, what works for one player won't for another.
In short, unless they have some way of keeping Folk informally as a back-up, this is a really big gamble.
