My comment about Blackmon was in reply to your comment that Juergens should be benched for making a football 101 mistake and that Blackmon should be playing instead of him (nevermind that they play different positions - inside vs. outside). I just pointed out that by your logic, you shouldn't want Blackmon to be playing either, because he made an even more basic mistake than Juergens.
I'll leave it up to the coaches who plays and cheer them all on. They see everything in practice that we can't see. It's apparent that Blackmon is being eased into the offense. If he were showing in practice that he should be playing more, then he would be playing more. His playing time will increase as time goes on.
