I totally agree with you. I couldn't believe they had him on the firing block. If they hadn't won that one game they were going to fire him probably the next day or following Monday. Would have been a huge mistake on the part of LSU. Miles is a really good coach period.
I think there are two ways of looking at this.
Pros:
Les is a good coach, he is generally a real good guy, the kids love him. He brings a toughness to the team that probably very few coaches do in the NCAA in today's game but he does it without being a jerk to the players or the media or other coaches. He understand the run game probably better then any coach in football, and not just college. His instinct of calling trick plays is probably a few levels above anyone else in the history of the sport.... yes, he has a super great knack of calling them.
Cons:
Can come off as not quite right, although this to me is a positive. Relies on the run game too much, and is reluctant to have the ball in the QBs hands, and in today's game that just isn't always going to result in wins. Has made some questionable hiring choices to go with most pretty good ones..... Crowton was disaster even though he was the OC for the NC, the two headed DC monster was bad, as was the Steele hire. Relies on the trick play to overcome obstacles as a replacement for not putting the pressure on the QB.
He is getting up there in age, I had no problem with them replacing Les this year but I also have no problem with him coming back. A plan needs to be put in place for a new guy at some point. The DC is potentially in a position to ease into that role.
The biggest thing that has hurt Les, is the early NFL draftees. You don't win championships with freshmen.... its not an excuse its just a truth and something that needs to be overcome. This year, the team is still young compare to normal programs but by LSU standards in the last 8 years, they are ancient.
The door is open for a run this year, they probably have the pieces, but they need to get better as well.... Bama does't care about any of this.
People saying Les is/was a bad coach are really not worth the time and really have no idea how hard it is.
