He was once one of the NBA's best rebounders; a vital cog in the Bulls' championship teams during the Michael Jordan-Scottie Pippen era. Now, he's just 'Dad'. And like any other father, he's chipping in with school activities. His daughters attend St. Patrick's School in Arroyo Grande, Calif., and they've got a big auction coming up.
Among the featured attractions? A collection of autographed shoes from Horace and his other famous championship teammates including Jordan. There are six pairs of shoes and each one is signed. The minimum bid is $1,000 and there is a reserve.
There's also a Pippen signed jersey.
Grant rounded the items up and has donated them to try and raise money for the school.
The auction went live last night at 5 p.m. and you can check it out here on eBay.
