I'm talking about the NFL as a whole, not just the wildcard round. There are plenty of QBs whose seasons have ended.
Look, I'm a huge Dobbs fan. I hope he has all the success in the world. But his arm strength isn't elite or something that will wow scouts. They see plenty of guys with arm strength like his every year. Only every couple years do they get to see guys with elite arm strength come through the draft. Right now there are probably only 2-3 guys in the NFL with truly elite arm strengthーStafford, Cutler, and maybe Flacco. Jamarcus Russel had one of the strongest arms ever. Brett Favre could throw darts until the day he retired.
Dobbs doesn't have one of those arms that just makes you stop and say "damn." It doesn't mean he has a weak arm or anything, but you'll find plenty of guys with arms just as strong in the NFL. Some teams have backups with arms as strong or stronger (not that it makes them good QBs necessarily, but Bray and Mettenberger both have arms strong enough for that throw). Hell, I can think of a division that has 4 starting QBs that have all made throws as impressive or more so in their careers thus far (the NFC South).
