"I loved it up there and my family loves it and it was just a fit for me," said Watson.
There were a number of things that prompted Watson to commit Cal.
"First, I've always loved Cal, so that's always been my dream school," said Watson. "Then Coach Ingram, their running backs coach there, we have a great relationship. We have great chemistry. When I was up there we got to interact and talk a lot and it was just a great thing. I felt like this was my home. I don't know, I just felt like I didn't have to go see any schools."
However, Watson wants to make sure he made the right decision.
"When I came back home I spoke to my mom about it," said Watson. "She said to make sure I made the right decision I need to open my eyes and keep my eyes open and experience other schools. I wrapped it up but I still want the opportunity to do that to make sure everything is how I thought it was."
So, Watson wants to take an unofficial visit during BYU's Junior Day to see what BYU has to offer.
"Oh yes sir, no doubt I'm still going to check things out," said Watson. "Next weekend I'm going up to Utah to visit BYU to see how the campus is and talk to the coaches and players and stuff. I want to keep my eyes open to make sure I made the right decision overall."
To get a desired recruit to commit soon rather than later, colleges will often let recruits know that a scholarship might not be on the table very much longer. Watson says this was not the case with Cal.
"Well, it wasn't really them pressuring me or anything like that," said Watson. "I really didn't care if any other running back committed. It's just that I've always wanted to go to Cal and the academics are really good. It was just a great opportunity and I loved it up there and my parents loved it. I just thought at the end of the day I might as well [commit] since it was close to home and everything. I just thought I might as well, and it didn't really have anything to do with pressure."
When Watson visits BYU next week, he won't do so alone.
"Oh yes, my mom is coming down with me and I'm excited," said Watson. "I'm very, very excited. I've been talking to the coaches a lot, and I'm very excited to see what they're bringing to the table."
So what would BYU have to do in order to sway Watson?
"Honestly, I don't know," said Watson. "I would just have to go up there and feel a vibe and see it all for myself with my own eyes and talk to the coaches and stuff. I honestly can't tell you what I would be looking for because I don't know. It would just have to be a natural feel of vibe."
Knowing how much his decision on where he'll play football will affect him, Watson is simply double-checking.
"This is for the rest of my life, so I have to be 100 percent on it," Watson said.
BYU is going to have to pull out the stops to show Watson that being in Provo would surpass his experience at Cal both on and off the field. It's a tall order, but Watson is excited to see what happens.
"They said they can do it, so we'll just have to wait and see," he said. "I didn't think it could get any better than Cal, honestly. So, BYU's gotta bring it!"
