The former Patriot has spent the last week looking for a home, including visiting Pete Carroll's Seahawks on Monday.
Thursday he arrived in Cleveland and met with team officials. By Friday morning, he had agreed to a deal.
Back in 2004, Watson was a first-round pick (32nd overall) out of Georgia and came into the league with a lot of hype.

With his speed and catching ability, he racked up a career high 49 receptions in 2006 and accumulated 29 receptions for 404 yards and five touchdowns last season.
