I don't worry about White tackling in the open field, and I couldn't say I felt that way about Gilmore. He used his length in coverage well, but he wasn't a great tackler (could be the Lacy incident, I honestly don't remember), couldn't shed blocks, and his technique was weird.
He was a fine corner. I wouldn't call him phenomenal then or now, but I liked him a lot when he was a Bill.
