I use a D5200 and a Sigma 70-200 mm F/2.8. One thing I have noticed when shooting at higher shutter speeds, if I leave the OS on I will sometimes get a noticeable blur on some of the final images. It doesn't seem to happen on all of them but it does seem to happen say as much as 20-30% of the time at higher shutter speeds. At first I assumed i was simply missing the focus point, etc - but after doing some testing I discovered that if I shut the OS system off when shooting at higher shutter speeds (1/500 and up), I don't seem to experience the issue at all. The images come out nice and sharp.
I can't say for certain your seeing the same thing since your lens is a Tamron rather than a sigma - but you might want to try the same thing and shut the VC system down when shooting at higher shutter speeds. Made a world of difference for me.
I will try that out as normally am around 1/500 but up it to make sure its frozen was above 1/1000, and must say recently i was having issues around 1/800 trying to image a bird that was just walking around and was terrible images yet the focus point was right on after checking.
