A player making contact and remaining completely on top of base but very briefly not actually having contact and being called out is just not 'right'. An over slide is a completely different thing. This. Overslides, over-running the base, those are completely different than Javy's slide. Again, I don't think the people who determined how replay was going to be used really considered a slight disconnect from the base. I look at it as a loophole that managers are exploiting. Especially since in instances like Javy's slide, it's incredibly subtle.
