All I know is at the end of the year along with Bazz, and Boat, Giffey was the only other player Ollie seemed to trust on the floor. This is in game tight situation (and there were a lot of them), and times when we needed to be in control of possessions and situations.
He was a senior with Championship pedigree and mucho experience. He did everything that was asked and NEVER choked or seemed over his head. Ollie even put him on Randle, an AA and top 5 draft pick, Giffey was effective. Kromah tried but couldn't do it. He may not be more important than Bazz but him leaving is huge, and we will find out how true this is next year. He is the new Rashaad, in that he may not get the notoriety but he is the key to winning our 4th Championship.
Rashad you are not the only 'silent' legend. I hope we fans talk about Giffey in the same breath we talk about J-Lamb, K-Free, Ricky, Jake, Taliek and all the other important player components essential to winning Championships.
