Webb said Tuberville's move "definitely" changes his mind on the Red Raiders.
"Last week I thought the offensive coordinator was going to leave but I was thinking about staying committed but possibly exploring my options a little bit, but when Coach Tubberville left, that really opened it up," said Webb who is ranked as a three-star quarterback by Scout.com.
For Webb who plans to enroll a semester early at his college of choice, a decision must come quickly.
"I'm going to take 1-2 visits in the next week, but here's the thing for me as with most recruits, February 1st in national signing day. I am graduating high school in two weeks. so I've got to make a decision very quickly."
"A lot of guys are staying on board [at Tech], and I could stay on board, but I don't know yet. We'll see how this week goes with the coaching search, and I'll make a decision."
Webb said TCU was one of the first schools to extend him an offer, and he has continued to hear from the staff.
He said he will visit TCU this week.
I am still verbaled to Texas Tech, but you can't be committed anywhere without a head coach. I'll explore my options. I have some calls from some other places, and we'll see what happens."
"All those places have great coaches on and off the field," Webb said. "When Coach Tuberville had to leave, who knows what's going to happen with those [assistants]. I am looking around and a lot of schools on my list have really good coaches which is a great thing to know."
"In the spring, I told my dad that there was one school I wanted to go to if they offered me, and that was Texas Tech, so I committed the day they offered me. I didn't really have a chance to visit anywhere after I committed."
?Webb said he did visit several Texas schools, however, before he committed.
He said, "I've visited basically every school around here just not schools like Indiana, Iowa State, or Iowa."
Webb said having not visited would not prohibit him from committing to one of those places because "I'm legitimately interested in them, and I think they know that.
"Right now I'm open, and we'll see how things go this week."
Webb pleased with senior season at Prosper.
"It was my first year at Prosper. I think the thing I most improved on probably from last year was my running ability. I ran tougher, but most importantly, I won a lot of games (10 games this year). I proved I could be a winner, and I can lead a team to victory, not just throw the ball pretty good."
"At Keller we had a lot of injuries, but having Torii and Money Hunter to throw to make a lot of things easier. I just had better football players around me. As a quarterback, you are only as good as the other guys around you."
Webb is ranked by Scout.com as no. 36 quarterback prospect in the class of 2013.
