The 6-foot-2, 185-pound quarterback also had an offer from Western Michigan but once he got his offer from Iowa State his recruitment was pretty much over.
"I'm originally from Iowa and most of my family lives there," said Rohach. "My parents went to Central College and I already have cousins and other relatives that go to Iowa State. I went to their camp last summer and I just loved everything about it."
So what do the Iowa State coaches love about Rohach?
"Coach Elliott told me that they feel like I'm a great fit for their program because we run a very similar spread offense at my school," said Rohach. "He said they feel I'm a good player that could add a lot and he also likes that being from California that I already know what the state of Iowa is like."
Another key part of making his final decision was getting to know Iowa State offensive coordinator Tom Herman.
"He has already come to my school and so that's when I met him," said Rohach. "My offensive coordinator at my school was actually college roommates with Coach Herman."
Grant also clearly likes where Iowa State head coach Paul Rhoads is taking the program.
"I really like what he has done and like how they play football," he said. "I met him at the camp and he's a real stand-up guy that I look forward to playing for him."
So what does Grant consider to be his strengths at quarterback?
"I feel I'm very consistent at doing whatever it takes to help my team move the ball down the field," he said. "I'm not the type of quarterback to try and force things down the field if things aren't open. One key part of my game is that I rarely turn the ball over."
His 2010 statistics clearly back this up as he threw for 21 touchdowns and only threw five interceptions. He was 174-274 for 1,867 yards and he also ran for 331 yards and seven touchdowns.
Grant Rohach will next visit Ames for the Iowa State spring game.
