Most improved returning players?: Lattin and Woodard
Biggest impact newcomers?: My picks would be Buford, Odomes and McNeace, in that order.
I gave some thought to adding Manyang to the newcomer list. But, since I have said for sometime McNeace will surprise some people before he's through, he's in my top three. It might not be this year. But, I think Jamuni has the potential to be a major factor on this team by the time he's a junior (third season), and it wouldn't surprise me if the lights come on in the next year or two.
To me, the best thing about these questions is that there are so many players to choose from this year. That's a credit to LK and his staff and the kind of talent they are bringing to OU now.
