The two realize they are the cornerstones of the franchise and Houston's football success is directly tied to their own.
Tunsil and Watson are spending time motivating each other, even in the midst of a pandemic.
"We basically just tell each other, 'let's go get it, let's get it done'," Tunsil said. "We've got the tools right in front of us on this team and we can get it done. It just starts with us. We pretty much voice our opinions every day about the team we have."
Tunsil admitted the Hopkins trade hurt. Hopkins was one of the leaders on the team who took Tunsil under his wing when the Texans traded for him from the Miami Dolphins shortly before the start of last season.
It's part of the business, Tunsil said, and there's nothing he can do about it.
Tunsil just knows he's on his own quest for greatness, both on the field and at the bank.
The three-year deal was important to Tunsil so he could re-enter the free market in short time, possibly to set another record deal for his position.
And all of the money his own.
Tunsil thinks he may have helped start a trend by negotiating his own deal, without an agent.
Players he heard from around the league were surprised to see him get such a favorable deal done on his own, but Tunsil said the toughest part was just learning terminology and being able to articulate it to the other side.
So Tunsil will continue to bet on himself. When this deal is done, he'll be 29 years old with an opportunity to get paid again.
This is a long way way from where was four years ago on draft night, when he was humiliated by a leaked video of him appearing to use marijuana through a gas mask.
Tunsil was considered to among the best players available in the 2016 draft, but he fell to Miami at No. 13 overall as the video went viral on social media.
"It's a huge blessing. Definitely coming from what happened on draft night and to be here now," Tunsil said. "They tried to bury me and I overcame that and I'm here now. To all of those people actually going through adversity, never quit."
