I actually think that Granger and Dunleavy's injuries might be more related than people might think. Chronic tendinosis leads to tendon calcification. I believe it's entirely possible that Dunleavy's bone spur could have started as a complication of chronic tendinosis, but I could never find any literature to back up his suspected etiology. I'm pretty certain that I remember reading that Dunleavy's bone spur was unusual that it was embedded in his patellar tendon.
Doesn't matter... both of their knees aren't 100%. I continue to hope for the best for Granger, but I also am trying to keep realistic expectations given the circumstance.
