Young played with the starting unit in practices on Wednesday and Thursday.
"I've got to keep on working to get better every day," Young said. "I know that it's still early and I know that I've got a lot to learn. I was absorbing it from the sideline and now I'm out on the field taking it all in, so it's been full speed ahead. I'm just trying to impress the coaches every play."
The main challenger to the four-year veteran will come from Mike Adams, who can also play cornerback. Whoever gets the starting roll when all shakes out will be replacing Abe Elam, who has moved on to the Dallas Cowboys.
Browns' coach Pat Shurmur seems to be pleased with the prospect of having the veteran of the Saints' Super Bowl-winning team.
"We feel good that he's here," said Shurmur. "[The safeties] have to be able to work together, take charge and communicate well. And then you typically play on the weak side, so you've got to be able to come up and support the run. That's what we're looking for. We feel like [Young] can do that. We were impressed with him watching him play."
