LUBBOCK, Texas (AP) -- A son of Texas Tech coach Bob Knight says he made a mistake assuming that the rules that apply to merchandise exchanges between stores in the private sector are acceptable at a store operated by a university.

Athletic director Gerald Myers announced last week that Tim Knight inadvertently violated Tech policies but broke no laws in the exchange of merchandise between "The General's Store'' in Indianapolis, which Tim Knight owned, and the "Double T Shoppe,'' which Tim Knight operated for Texas Tech.

"Nobody made any money in this transaction because it was all done at cost,'' Tim Knight told the Lubbock Avalanche-Journals for a story in Sunday's editions.

Tim Knight sent about 900 miniature basketballs, some caps and media guides from the Double T Shoppe to the store in Indianapolis, which was operated by his mother, Nancy Knight. In return, the Indianapolis store sent a number of items, including pictures of Bobby Knight, to the Texas Tech shop.

The Double T Shoppe received no money for the items sent to Indianapolis, and paid nothing for the items it received from Indianapolis, officials said.

That was a violation, but Bob Knight told the newspaper that the story was blown out of proportion.

"Tim was never in a position where he owed the university more than the university owed him,'' he said. "That's never been brought up.''

Each side has now paid for merchandise received, with neither paying more than cost value for any merchandise, Tim Knight said. The school still owes him approximately $7,000 for T-shirts he purchased with his credit card during the basketball season, Tim Knight said.

Records show that $4,067 in merchandise was shipped from the Tech store to the Indianapolis store and that $8,960 in merchandise was shipped from Indianapolis to Lubbock.

During a Tech investigation, someone identified as an administration official said Tim Knight had been removed from his duties overseeing the Double T Shoppe.

"That's absolutely not true,'' Bob Knight said, adding that his son had asked to be removed from those duties before the transactions came into question. Tim Knight said his other marketing duties at Texas Tech had made it difficult for him to devote sufficient time to the Tech store.
