Oh man, "Over-Reaction Monday" gets here on Fridays during the off-season!
One of Pete's core competencies as a coach, that he does better than any other coach in the NFL, IMO, is to lead a staff and environment that rapidly coaches up and develops young guys into NFL-quality players. ("Rapidly" includes redshirt guys who emerge as NFL-quality players in their 2nd and 3rd years)
As Spin Doctor put it, "We're relying on a lot of young guys who haven't exactly shown anything in the NFL yet to step up for us. I think the biggest area of failure was at offensive line this offseason and we haven't done much to address our weak defensive line."
While I think our O-Line is going to be a surprise strength, our D-Line, especially DT spots, are looking a bit shaky right now.
But yeah, we are relying on a lot of young guys who haven't exactly proven anything in the NFL. Pete's redshirt classes. So it will be Christmas in September? (As in DeMarcus, the redshirt DL) Will LJ start Colliering QBs? Will Tre Flowers truly blossom in his 3rd season? Jordan Simmons HAS proven himself as a player in the NFL, but hasn't proven he can stay healthy. Will BBK emerge as an NFL-level player? Our TE meeting room wil be *fascinating*, will Uncle Will ever be back to impose his will? Our 7th rounder, will Greg Olson turn him into a force of nature? Will Cliff Avril come on board and coach up our two edge rusher draft picks?
We also don't know what scheme adjustments Pete and Schotty and Norton are in the process of making to take advantage of personnel. More up-tempo offense? I think we get so focused on players and talent acquisition it's easy to overlook scheme changes that can make a real difference. That stuff is part of the offseason too. Don't overlook the culture of buy-in among the players that Pete & Co have going on here; in a season disrupted by Covid-19 lockdown, that could make a big difference.
The other point I think is being overlooked here, is DEPTH. We were injury-decimated at the end of last season. If our practice squad TE gains 18 more inches on that play, we still Freakin WIN THE DIVISION, over a 49ers team that had a double-digit 4th quarter Super Bowl lead. Carroll & Co. were plugging leaks left and right. When our stars are unavailable, do we have guys ready for "next man up"? Guys who can at least play at an "average" NFL level, or is there a huge dropoff? So, IMO, panning the pickups of guys like Benson Mayowa and Bruce Irvin misses the point. We lost SB49 when Cliff Avril went down with a concussion, as much as we lost it on "The Pick". Nobody else was able to generate pressure. And NE "disappeared" Chris Matthews in the 2nd half, and repeatedly torched sucky Tharald Simon. Have Carroll and Schneider done well at acquiring/developing quality *depth*, without overpaying? In 2013, we steamrolled the opposition because we had a ton of young guys, and veterans, outplay their contracts by a wide margin. IF Quinton Dunbar plays, he's one of those guys who has the potential to outplay his contract by a factor of 2X or more.
TL; DR;
When grading the offseason, also pay attention to quality of depth across the roster, and guys who are primed to significantly outplay their contract. A serviceable "Next man up" is as likely to win key games, or, more accurately, not be the "weakest link" glaring flaw opponents can repeatedly exploit to defeat us.
