I'm a pretty realistic person, but it sounds like Matt is back to form. God knows what'll happen when he starts to get hit, but early indicators are very positive. Here's an excerpt:
When the Seahawks gathered for their team stretching drills, I saw one contortion that would convince even the most skeptical fan that Hasselbeck is fully recovered.
The players lay face-down on the grass, arms out to the side. They lift their left leg back up into the air and rotate it around to touch the ground on the right side of their body. Then they roll back and do the opposite with the other leg. It looks impossible for any vertebrate mammal other than yoga instructors.
The fact that Hasselbeck executes the stretch without becoming knotted or tearful is testimony to his health.
