There can also be the point that DSLRs have better weather sealing than mirrorless, but there doesn't seem to be any inherent limiting factor of mirrorless that impedes the implementation of weather sealing, but rather just at present mirrorless cameras do not have weather sealing as good as a DSLR (though that could very well change in the future). As such sports and action photographers generally opt for OVFs which can only be had with DSLRs. With an OVF, you can see action as it happens, whereas with EVF, they generally have a tiny bit of lag and as such the image you see through the viewfinder is more of an "afterimage" than a true view of what is happening. DSLRs tend to be more responsive as well. You could stick that on an A6300 and get an equivalent FoV of 450mm at the long end, but that still does not match up to a 600mm lens, which on an APS-C body produces a whopping 900mm (Nikon) or 960mm (Canon) equiv.

The longest Sony offers for Full Frame mirrorless is their recent 70-300 zoom. Canon and Nikon both have their share of 300, 400, 500 and 600mm lenses. For example, those huge telephoto lenses that sports photographers often need are only available for DSLRs. It is generally well known that the large DSLR systems cater better to these needs. People that shoot sports and fast paced action tend to be very demanding on their system. Some however, prefer cameras with large grips over small size, and thus go for DSLRs. There are some photographers that like using the A6000, and now the A6300, because they are such small cameras with such high burst rates. Some may also be under the impression that DSLRs are just plain better than mirrorless because that's what seems to be the dogma that the online photography community generals passes around as "fact". Some people prefer to shoot with a DSLR, possibly because they grew up shooting film SLRs or even the early DSLRs. Your question can be answered in three points: I think the A6300 shows a lot of where Sony is heading with their FF mirrorless cameras. Probably coming full frame mirrorless cameras from Sony will do sports and action very well, hopefully at the same level as the best DSLR cameras. I am sure many could do pretty well with cameras like the A7rII and even the A7 and the newer A7II cameras for a lot sports and action shooting, but the older models can not compete with higher end DSLR cameras when it comes to tracking focus.

There is a difference in shooting technique with ovf versus evf, but much of this can pretty easily be overcome.

If you are used with an electronic viewfinder and have trained a bit on following moving subjects, or panning action, you should do pretty well. But then, how close can you get, and how much cropping are acceptable? Also, indoor, outdor daylight or night?

Tracking autofocus might be a limitation compared to the bes DSLR cameras, and so might the lack of bright long lenses. Many shoot high frame rate bursts, but surprisingly many experienced photographers shoot single frame or very short bursts. This depends a lot on your shooting style and what sports and action you are going to photograph.
