That's exactly what I think best case scenario Norman performs in this defense, the difference being Sherman doesn't have a White opposite him nor Edmunds/Poyer brackets to assist.
Here's a primer on contact tracing (you'll note there is a confidentiality aspect- no names are included as part of the traceback): https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/contact-tracing.html
Also estimated only 40% of symptomatic COVID-19 case contacts need to be identified and quarantined to manage spread, your examples are unlikely to constitute >60% of a symptomatic person's contacts: https://www.statnews.com/2020/05/29/contact-tracing-can-it-help-avoid-more-lockdowns/
Sherman benefitted a lot from that dline in front of him, he made hay w/his smarts and strength but he doesn't have the agility to be a top corner anymore.
The route running is inarguably in favor of Diggs. I suppose breaking tackles would be an area where Thielen is better because he is bigger/stronger, but you will be hard pressed to find anyone outside Minnesota who thinks he's the superior wideout in any respect imo
Keenan Allen is just Hopkins-lite to me. Incredibly reliable, soft hands, not a real physically dominant presence but usually open and very respectable YAC option. He's a very reliable WR1 but if top 10 is elite guys then he might miss the cut.
