However, the unanswered call gave Knox time to re-think his decision and for now he's put his commitment on hold.
You could say recruiting isn't the primary focus for Knox at the moment. After all, he's helped Ft. Worth All Saints to a 7-0 record with just two games remaining in the regular season. The closest any team has come to beating the Saints is Arlington Oakridge, who lost 31-21, but that was after trailing 31-7 in the fourth quarter.
The season has gone pretty much as expected according to Knox, but this year they have to finish the task at hand to bring home a championship.
"Most of the people on our team went to the championship last year are still here so we're used to this," he said. "Now, it's just finishing it this year. We're trying to take it home and get a blowout in the championship this year."
Last season the Saints lost twice to Oakridge, once in the regular season and then again in the SPC Championship game. It was nice to have a little payback according to Knox.
"It was a great feeling, it was beautiful," he said of beating the Owls.
It's hard to judge a lineman based solely on knockdowns or pancakes. For Knox, one just needs to look at the production of his pal Gresham, who is fourth in the DFW area in rushing with 893 yards on only 74 carries. That's an amazing 12 yards per carry.
"It's crazy, he's having a great season right now and everything. He's always coming up to me and telling me how thankful he is," Knox said of Gresham.
When Knox does have time for recruiting, he's taken in a few games including last week's Red River Shootout between Texas and Oklahoma. Knox said despite the outcome, the Longhorns remain his top choice for reasons beyond just football.
"We went to that game," he said. "Right now Texas for me is still my #1 school. But, there's more than just football; do we feel comfortable and what's the environment and everything. I feel like I connect with their entire coaching staff, it's more than just football."
"Every time I go there they treat me like I'm on the roster," he said. "They're really high on my list too. I won't make a final decision on committing or anything like that because I'm in love with them too right now."
Knox said he noticed the Frogs' 49-21 win over Baylor but unlike most, he wasn't surprised with the outcome despite all the adversity the team has faced.
"They're a really good team and I expected them to be really good this season," Knox said of TCU. "They've got a backup quarterback right now and I think he's going to be pretty good too."
TCU has played fifteen true freshmen this season so they've proven to recruits that playing time goes to the best player, despite the experience. Knox said it does have a small impact to play early, but at the same time he's fine with learning the ropes from more experienced players if need be.
"Yes and no. Yes because all of my life I've pretty much been spoiled with the whole aspect of starting and all of that stuff but I haven't really experienced it with three or four tackles and we're all fighting for the same spot," he said. "I'd love to start early but at the same time I'd like to watch the older guys and learn some techniques from them and pick up others stuff along the way to help me too."
One person in the Frogs corner is Knox's mother, who he says has made it apparent where she would like him to go, mainly because of proximity. However, Knox said she knows it's his decision and will stand beside him no matter where he decides to go.
"She's in love with it," he said of TCU. "She really wants me to go to TCU and everything but she's telling me to do whatever is best for me."
Alabama is another school that has showed Knox heavy interest. He went to the Bama-Michigan game earlier this year when they played in Cowboys Stadium and the coaches recently came to one of his games.
"Big time, I talk to their coaches every week or two and I have a good rapport with them too," Knox said of the Crimson Tide's interest.
Knox has added two more offers in recent weeks and said others are soon to follow.
"On the 13th Oklahoma offered me and Ole Miss just offered me," he said. "Florida State, Oregon and USC I'm talking to a lot. Oregon basically told me that I have an offer once my junior year is up. Florida State and USC is about to offer me."
The 6-foot-5, 305-pounder might be in attendance for TCU's game against Texas Tech this Saturday. If he doesn't make the game, he will attend the Kansas State game on November 10th.
