Saw a bit of it. Rusty sure. But he seems to have lost a bit of power. Didn't look like he could generate the usual velocity on his shots as he could before. Could be rust though, as you said.
Most notably, I feel like his athleticism looks a shadow of itself. It's too be expected, but I don't think it was ever this bad previously. He looks way slower, not just in speed, but in movement.
I honestly am just happy to have him back. Don't really care if he wins. Just as long as he sees himself to retirement without another major injury,
