He says in the interview he calls them.
I still don't understand why people are so up in arms over Sears. It was an interview predicated on Lazard's commitment to Iowa State. So yes, he should give Lazard several chances to say multiple times he won't be going elsewhere.
If it was an interview about what he wants to accomplish next year at Iowa State and Sears kept asking about his commitment to Iowa State, then that would be out of the context of the purpose of the interview. Again, the interview was about his recruitment and commitment to Iowa State.
Not sure who recruited him from ISU, but with the season we are having, if I were a hot recruit. I wouldn't burn any bridges at this point. Not because of Ws and Ls, but in case there are some big changes in staff after the season that I'm not comfortable with.
