One area the offense appears to have upgraded is at slot receiver, with the addition of veteran Randall Cobb.
The Texans signed Cobb as a free agent this offseason for three years, $27 million.
Cobb was productive last season with the Dallas Cowboys, posting a career-high 15.1 yards per catch and 10.2 receiving yards per target, the most since his lone Pro Bowl season in 2014.
It's important for Cobb and quarterback Deshaun Watson to build a rapport, but they've faced challenges since he was signed in March, due to the COVID-19 pandemic.
Cobb on Tuesday estimated he and Watson have been able to throw to each other five to seven times, and said they're doing their best given the circumstances.
Decision-making is a key element to the Texans offense, and Cobb said he feels comfortable with the information thrown his way up to this point.
But it will take time to develop the chemistry with Watson, he said. That doesn't just happen overnight.
"I'm just trying to continue to get comfortable. Obviously we haven't had the opportunity to build the chemistry I would like to over the offseason, given we've only had a few days to work together," Cobb said. "Obviously, we're pressed for time with the situation we're in right now. But we're talking through everything and I think that's a big part, is communication and him being comfortable and trusting in me, knowing I'm going to be where I'm supposed to be, when I'm supposed to be there."
Watson spoke over the weekend about building chemistry with all of his new weapons -- Cobb, Brandin Cooks and running back David Johnson.
Cooks joins Will Fuller as a viable 1-2 punch of excellent route runners with breakneck speed.
With Johnson joining David Johnson in the backfield, there's no telling who's getting the ball, as Watson mentioned Saturday.
Cobb said he sees unlimited potential in Watson, a raw talent who is still growing.
"You get that (knowledge) from experience," Cobb said. "You get that from being put in different situations and scenarios, understanding when it's time to take those chances and when are the times, third-and-long, dump it down and punt the ball away and wait for your next possession. It's all a learning curve and it's all an opportunity to continue to grow.
"I think it's talking through blitz pickups and understanding the hots (reads) and being on the same page with those. It's understanding the coverages and the way certain teams play the coverages, finding those holes and being able to fill the voids. I think that I've, over the time, gotten a pretty good rapport with my quarterbacks just being able to talk through those situations. Having a little bit of a quarterback background myself, and understanding it's not always about getting open, but getting open at the right time.
"So, understanding where you are in the progression as a receiver, that's some of the things I want to make sure that I'm letting the young guys in that room know. Obviously, it's a little bit different right now because we're all in different groups and we really can't meet in the meeting room at the same time right now. But really, just understanding the game from a big picture and not just from our position and understanding where fit into the puzzle."
