Because the Chaz Green example is a text book example of how it was 100% coaching that was the problem. Chaz Green is and was terrible. Any fool could see that.
Yet he played well the previous year filling in for an injured Tyron. It's easy to say now that he was just always bad, but the fact is he was a serviceable backup in 2016.
-Chaz Green should have NEVER been on the team. We saw first hand how the Cowboys went out THIS offseason and made sure they had quality backups. And it paid off this year.
His horrible play wasn't apparent the previous year.
-Garretts...………"next man up" stupidity was at the heart of the issue. Thinking that some scrub like Green could just come in whenever and NOT plan for help the possibility of help was a huge mistake.
They gave him help at times but you can't help a tackle every snap. Again, his track record prior to that game wasn't that of an awful player. Typical backup level. Nobody saw that performance coming.
-The fact that it took Garrett and the staff sooooo long to make the adjustment DURING the game was pathetic. So the coaches failed on all 3 levels
What happened when Bell came in? He performed as poorly as Chaz. Sometimes you have to pick between a bad option and a worse option.
1. Evaluation 2. preparation 3. Adjusting during the game.
Chaz wasn't the only issue that game. He's just the easiest to remember. Regarding evaluation, you say he shouldn't have been on the team but his performance prior to that game was of a servicable backup. Gotta have them and someone picked him in the 3rd round so he was going to get a chance to show his worth.
Regarding prep- How does a coach prepare for a complete breakdown of a player? A backup player at that. Adjustments- Chaz defied the laws of probability that game. No one expected that poor of a showing and when the trigger was pulled, nothing got better. Sometimes you're stuck with the players you have and you have to hope they can execute the next play because the other options are worse.
