Is Chalks commitment solid

"After I committed to Iowa State schools were still recruiting me for awhile," defensive back Bobby Chalk said. "But they've stopped now."
"I'm not going to visit Wisconsin. I don't plan to visit anyone except Iowa State."
"I'll visit Iowa State the weekend of Dec. 5. That will be my only official visit."
The 5-foot-9 and 177 pound Chalk, from Garland, Texas, was a second team all-district selection his junior season. He has helped lead Garland to an 8-3 record and a spot in the playoffs this season.
