The 6-foot-3, 190-pound quarterback also had offers from Tulane, North Texas, and Middle Tennessee but his decision completely came down to two schools.
"Wake Forest has also been recruiting me real hard and I believe they were close to offering but I just felt Iowa State was the better fit for me," said Richardson. "Making a decision before my senior season was just something that I wanted to get done and so I talked it over a lot with my coaches and my parents. It has really been Iowa State with me for a while now and I'm just excited to be a Cyclone."
Sam told Cyclone Sports Report that a visit to Iowa State this summer was a huge factor in his commitment.
"Coach Messingham and Coach Herman had come down to some of my practices and they wanted me to come up for a visit this summer so I decided to go up for one of the one-day camps," he said. "So during the camp they saw me throw and they liked what they saw and so I got an offer shortly after that camp."
During his visit Sam also hit off very well with the guy who will now be mentoring him at his position during his career at Iowa State.
"Coach Herman and I had immediate chemistry and we for some reason we just connected," said Richardson. "A lot of the terms we use are the same and I can just tell that working with him will make things a lot easier to understand in regards to what they are doing on offense."
Sam was also influenced by some fellow Floridians that he met during his visit to Iowa State.
"I talked with Shontrelle Johnson and Donnie Jennert who are from my region of Florida and they both told me good things about Iowa State," said Richardson. "It seems like we're starting a pipeline from Florida to Iowa State."
He also did his homework and realized that Iowa State's starting quarterback (Austen Arnaud) will be graduating at the end of this season.
"It's something that I looked at closely and I definitely like the fact that I will have the opportunity to come in and compete for playing time early on in my career," said Richardson. "It really comes down to the fact if you can play you are going to play and the competition should be a lot of fun. I'm really looking forward to it when I get there next year."
While Sam hit it off well with Coach Herman, he also can't wait to play for Iowa State's head coach.
"I really love Coach Rhoads as a head coach," said Richardson. "He's a great guy to talk with and he's big on me and I'm definitely big on him. Playing for him is something that I'm really looking forward to in the future."
Sam has also set up his second trip to Ames as he will be attending the UNI game on September 25th for his official to Iowa State.
