According to both Rivals and Scout he was a 2-star recruit that had only one major offer... Illinois. He was interested in Mississippi, Missouri, Texas A&M and Wisconsin but did not get an offer from any of them. Therefore, he probably does qualify as a stretch.
Now, Turner may have seen something he really liked in the guy but Turner also had a tendency to recruit lots of quarterbacks and converted many to other positions.
I'm glad to see the kid did very well after transferring but it really doesn't look like he was heavily recruited in Texas or anywhere else.
