AND for the thousand's time, "alpha WR's" are great to have. It's not that I wouldn't want to have one or two, but you don't NEED one to be a championship team. Think about all the alpha WR's who never won a championship.
Its arguably the 2nd most important position behind QB. When you look at the money teams are spending, resources they use to acquire them, impact they have on the field They've become as or more important than any position save QB. Most will say tackle bc that's what they're used to saying but game hS changed. Also anyone that knows even a little about about OL understands you're looking to "survive" as opposed to "win." Mainly bc defensive players are more athletic and quicker. So you don't need elite there although no one would ever complain about having a OL. You simply can't get away with "surviving" at WR in 2024.
Back to your post above, specifically about superbowls. I dont want to get into an argument involving semantics but there's little difference between WR1 & TE1. Even usage especially given how much more the slot position has evolved. Let's look at both teams though. Here's 10 or so, recent history for obvious reasons. Mostly WR1 types. Monster slots in Kelce and Ertz. More traditional Y in Gronk and Olsen. These are all top tier players though. Especially during that specific year. As good as it gets.
24 - Kelce/Deebo or Aiyuk
23 - Kelce / Brown
22 - Kupp /Chase
21 - Evans / Kelce
20 - Kelce / Kittle
19 - Gronk / Woods or Cooks (both had 1200+)
18 - Ertz or Jeffrey / Gronk
17 - Gronk / Jones
16 - Thomas or Sanders / Olsen / Ginn
15 - Gronk / Baldwin
14 - Baldwin or Tate / Decker or Thomas
Let's look at points, yards, total yards ...
Top 12 in points (no order)
Miami - Hill, Waddle, Wilson
49ers - Aiyuk, Deebo, Kittle
Lions, Jamo, ASTB, LaPorta
Bills, Diggs, Davis, Kincaid
Cowboys - Lamb, Cooks, Ferguson
Ravens - Flowers, Beckham, Andrews
Rams, Puka, Kupp, Atwell
Phila - Brown, Smith, Goedert
GB - Reed, Wicks, Doubs
NO - Olave, Shaheed, Thomas
Cleve - Cooper, Moore, Njoku
Indy - Pittman, Downs, Pierce
Top 12 in pass yds
Miami - Hill, Waddle, Wilson
49ers - Aiyuk, Deebo, Kittle
Lions, Jamo, ASTB, LaPorta
Bills, Diggs, Davis, Kincaid
Cowboys - Lamb, Cooks, Ferguson
Minne - Addison, Jefferson, Hock
KC - Kelce, Watson, Rice
Houston - Collins, Tank, Schultz
Jags - Ridley, Kirk, Engram
Rams, Puka, Kupp, Atwell
GB - Reed, Wicks, Doubs
NO - Olave, Shaheed, Thomas
You could argue 9/12 teams have legit WR1 with a lot of WR1B & WR2.
Few teams from 2022-23
points, total yards, pass yards (no order)
Detroit - 5 points, 3 tot yds, 6 pass yds
Minnesota - 7 points, 7 tot yds, 5 pass yds
Philadelphia - 2 points, 2 tot yds, 9 pass yds
Buffalo - 4 points, 4 tot yds, 8 pass yds (only played 16 games)
Miami - 11 points, 6 tot yds, 4 pass yds
Las Vegas - 12 points, 11 tot yds, 11 pass yds
Seattle - 9 points, 12 tot yds, 12 pass yds
KC - 1 points, 1 total yds, 1 pass yds
Jags - 10 points, 9 total yds, 10 pass yds
More than half have WR1 with a good amount of WR1B / WR2.
Between both years, most, if not all. Are WR1 types. These guys are so good it'll fluctuate slightly year to year but no one would argue the majority of these teams don't have legit top-tier, top 3-10 WR. And lots of WR1B/WR2, which is just as telling. Teams know you need more than one top-tier player getting targets to get to where they want to go.
Back to your post above. You're certainly not approaching real success without special targets. Even if the position changes, it doesn't matter. You need a HOF caliber TE Kittke, Gronk and Kelce to replace that WR1. With quality options behind them.
OL is still key and extremely important. Obviously QB is king. Top tier TE are very clutch. WR has really craved out a spot for itself when you look at how much teams are passing, the rule changes and evolution of the player, physically. Everyone is a freak now. And the usage and role. It's changed dramatically in those regards over the last 30 years.
Whether its getting or winning the SB. Being top 5-10 in points, yards. WR have become as important as any position besides QB.
