Then make it 30 feet from home. Or 20 feet. The point is, if there's a defined area where the baserunner is supposed to be and where the catcher is supposed to be, it would make things go more smoothly at home plate. I'm not against contact, but the current situation seems closer to chaos. The catcher is still going to block the plate, so how does this help? There is a defined area for the baserunner, they have to be able to touch the base, so that defines where they can be when coming into home. Maybe we should just make it always a force out at home? But then why stop there, all tag plays are riskier than force plays, so let's make it always a force at every base. But then, guys get injured sliding and diving into bases too (remember Jenkins foot practically falling off his leg), so let's allow the runner to over run the base at second and third, just like first. One reason there are collisions at home is because, unlike second and third, you can run right through the plate. There is no need to slide in because you do not need to stop on the plate.
