No one gets a ring by themselves in a team sport. You know this.
The ring stuff seems to play out in real time, but over time, not as much. I remember in the 90s when Barry Sanders and Emmitt Smith were the unquestioned top 2 RBs, and the debate always seemed pretty even about who was better. But now, unless you are a Cowboys honk, the answer is Sanders, and it seems to be not even close anymore.
Circling back to Herbert, let's look at him and another QB from his draft class:
Justin Herbert: 20-20 as a starter, 82 TDs, 30 INTs, 7.2 career YPA, 8 rushing TDs
Tua Tagovailoa: 19-9 as a starter, 42 TDs, 18 INTs, 7.2 career YPA, 6 rushing TDs
Herbert has a slight edge in stats due to a better TD-INT ratio, but Tua has a far better W/L record. Wins and losses supposedly matter more when it comes to QBs, but apparently not, as every time I see a football talking head do a list of the best QBs in the league right now, Herbert is either in the top 5 (usually at 4 or 5) or close to it, while Tua is not even in many top 10s.
I think Herbert IS really good, and will have a very good NFL career, but he is being put in a conversation with proven commodities already, which seems more than a bit premature. Can he get a winning record as a starter first? Can he win a playoff game? Heck, can he MAKE the playoffs first??
