A few years back, I went to a clinic by J.D. Blair. J.D. gave a young man the opportunity to play on his kit. He said to the young man, "give me a 5-minute groove." The young man proceeded to play a beat, and then started adding all of these fills and even changed the basic groove up every so often. J.D. just walked around the stage patiently not saying a thing or even reacting. He let the guy go for a full 5 minutes.
Once he was done, the drummer kinda sat there like "yeah, I just put it down" and even a few in the crowd showed approval for what he just done. J.D. simply said, "you can play, but I asked you to give me a groove. Not bragging, but I already knew what was up. He didn't outright dog the guy, but he basically went on to touch on the subject that seems to be a constant sore spot for a lot of the younger players.
I suggest as always that you study the art of groove from Clyde Stubblefield and John "Jabo" Starks. They may not "blaze" all of the time, but there is a reason that they are two of the most sampled drummers of all time.
It doesn't matter how cold your licks and fills are if you can't come back in on the one.
