I don't mean rebuild in the sense of tear it down and rebuild. I mean a soft rebuild which is what Loomis called it. I'd rather speed it up by parting ways with Carr, Mathieu, Jordan, and Hill, but they can still rebuild while maintaining a competitive team. But, I honestly don't see the huge difference if this is the last year for Carr, Hill, Jordan, and Mathieu. And even this year, Jordan and Mathieu took pay cuts and I expect Hill will as well.
The key either way is to draft better and then have the coaching staff to develop those players. Frankly whether they tear it down or they continue trying to be competitive, neither is going to work if they don't start drafting better and just draft more players. And, IMO, the draft is how you build a team. Cap money and free agency should be used to sign your own good players to 2nd contracts and to fill in holes before the draft so you can take BPA. But, first, you have to draft players that are worth 2nd contracts.
And some of this, I think comes down to poor coaching. I'll give Kubiak and his people as pass since he was only here for one year, but it does look like a staff that either wasn't good at developing talent or wasn't good at recognizing that talent and playing them. Too often guys leave here a play better either because they were developed well enough here or because they just weren't evaluated properly and/or didn't get a chance to play. Hopefully Moore, and his mostly young staff with a lot of college coaches mixed in, will be better at those things.
As far as Loomis not firing DA, I just disagree. I think Loomis was going to fire DA at the end of the season but Gail felt pressure from the players and fans and pulled the trigger. It was probably the right call in the end, but I think Loomis would have done it at the end of the season anyway. FWIW, Underhill said that he thinks Loomis was going to fire DA at the end of the season and he just didn't believe in firing coaches mid-season.
