I'm less worried than others about the receiver position because I know the system and a good QB can make decent receivers look like stars. Washington is a great example. They made a coaching change after the 2021 season and brought in Michael Penix jr. to play QB in their new, wide open system. Their two leading receivers went from a combined 80 catches for 885 yards and 7 TDs to 154 catches for 2243 yards (both went over 1,000) and 16 TDs. These guys weren't superstars until they played in a pass friendly offense with a quarterback who could sling it. Statistically, their 2021 offense was even worse than Miami's 2022 offense.
I get what you’re saying here and your overall point is pretty valid, but UW’s receivers aren’t just decent players who broke out because Penix and Ryan Grubb arrived.
Penix never came close during his time at Indiana to having a season like he did last year at UW, and I’d argue that the gigantic improvement in WR talent was as big a reason as any for his 2022 season. Penix nearly tripled his previous single season best in passing yards and more than doubled his previous single season best in touchdowns last year.
Penix in 2020 at IU - 56% completions, 1,645 passing yards, 14 TD's, 4 INT's
Penix in 2021 at IU - 53.7% completions, 939 passing yards, 4 TD's, 7 INT's
Penix in 2022 with McMillan and Odunze at UW - 65.3% completions, 4,641 passing yards, 31 TD's, 8 INT's
Both Jalen McMillan (a high 4* and top 75 overall recruit in 2020) and Rome Odunze (a rock solid 4* and top 150 overall recruit by 247 in 2020) were blue-chip recruits who broke out in their 3rd year and both look like NFL prototype early-round talents. The arrival of Penix at QB and Grubb at OC obviously helped their production explode, but they’re both studs in their own right as well.
We have not been recruiting outside receivers the caliber of McMillan or Odunze in many years. But I certainly agree with your general point that the right system and a good QB can make decent receivers look like stars at the college level. Rambo and Harley are a great example from just a couple seasons ago.
