My GUESS ... is that Chad knows his teams ( pit and shop) so well that perhaps he's leaving them "unattended" or "assuming" they will do the right thing. I've made that same mistake myself - and paid for it. Lesson learned - be more diligent.
But some of the stuff on here ( welcome different opinions - not wrong - LOL ) is a little over the edge. The article provides zero proof that Chad himself went in there and installed some parts. Please. The thought of Chad signing off on illegal parts, or an OK with a wink just doesn't seem to make common, logical sense. One can think it, believe it ( that Chad would do it )... but it doesn't make it a fact.
I also remember the window fiasco... and Chad's fingerprints were not on it, the gloves didn't fit... but he took the fall, as the accountable person. Same for Gordon's "T-Rex" ... but not as harshly... mainly because it passed PRE-inspection and people were not doing their inspection jobs and it slid thru.
I don't particularly care for Chad... but I don't like to see a guy railroaded either. As Schmoopy mentioned... car crew chiefs, have been stretching the line, interpreting rules, and looking for and edge for as long as the sport has existed. It's practically expected of them. Check the history. Nothing new here.
And for the record, in case there is anybody alive who doesn't know this... Jimmy and Tony are very good friends. Tony has been happy for JJ's wins... and JJ has been extremely gracious in his handing over the title. So I'm not buying any of the "Chad and Jimmie just can't stand that Tony won" stuff.
Sh*t happens... but don't worry, it usually happens to me.
