I try to remember that there's often several audiences Geno has in mind for remarks like that. But if I try to put myself into his mind [yikes!] for a moment, he must have seen something in those early practices. What could it have been?
If I had to guess, he probably saw a mobile strong player who was unafraid of contact, and one who could also handle the ball at midcourt. She probably seemed more solid and more intense than any of the recent bigs -- Dorka, Olivia and maybe even Aaliyah. I'd picture a quicker version of Mama Stef. If I recall correctly, his remarks came before any of the injuries that season. He was looking forward to the return of Paige, and having Nika and Aaliyah, and a healthy Ice and Jana, along with Azzi and Caroline. In that context, he may have thought Jana would have an easy introduction to D1 basketball and would have been free to develop on a team where other shoulders would carry much of the burden. When I remind myself of the context, I'm not sure he was really overselling her so much as doing some confidence building for her. Events didn't play out the way he'd obviously hoped, and they changed the weight of those remarks.
