I didn't say just anybody could do it. I do think a decent number of teams have a player that could do it though.
You're just arguing about nothing right now. Either you think the PR/KR's are the best the team has to offer, or you don't. If you don't, then you're acknowledging that they're allowing less talented players into that position. And that's what I've been saying since the beginning. That a lot of the time there's a less talented player in that position.
I brought up DJAX because he's a recent public example (a week ago), of a more talented player being on roster, but not in the role. Coaches recognized that and let him take it over when he wanted it.
