Just hypothetical, but if, for example, they view Patrick as a better pass blocker, and Teven as a better run blocker... you dont think them having to plan for neither or both holds any water? As far as who they decide to attack with, or as a potential tell ahead of time?
Sure, this is a definite possibility. However, I think the SF defensive line is great enough that it doesn't matter who is in front of them, they're still going to get theirs.
Now, I will say I would definitely understand the gamesmanship if we were talking about a great or elite level player ala Trent Williams. If a guy like that may or may not play, then yeah, I could definitely see the reasoning behind keeping it quiet one way or the other. I've never watched Patrick and only a few games of Jenkins but I've never gotten the impression that anyone considers Patrick or Jenkins in that stratosphere of quality where it would make that much of a gameplan difference. But again, I'm a just a fan, not a coach, scout or GM.
I'm probably in the minority on this opinion and that's fine.
