Warner was cut as a rookie then had to bounce around the Arena league and NFL Europe. That's why his 2nd season in the NFL was at age 28. At least Dobbs has been able to hang around in the NFL up to now.
Harrison was a position player. A lot easier to prove yourself when you're guaranteed snaps even as a backup. QBs don't have that luxury. They only play if the guy ahead of them gets hurt or is inept.
Dobbs is actually ahead of Warner and Harrison's pace when you consider he's been able to stay in the league and as a non-position player he doesn't have a history of failure before success like Harrison.
It's foolish trying to say Josh is ahead of Harrison's pace since
in spite of his coming into the league undrafted from Kent State and (as the stories have it) almost clueless and struggling mightily he was still in a Pro Bowl by this point in Josh's career. If you were going to hedge the "position player" argument you'd have been better served not citing Harrison at all.
No. Warner was an undrafted guy from Northern Iowa. Right there Josh had a huge advantage over Warner having been drafted out of a major university. Warner had one initial offseason training camp tryout with a Packers team against Brett Farvre & Mark Brunell. He was released before the season ever started. And he didn't "bounce" anywhere. With no league options he went to the AFL and put together two consecutive 1st team AFL campaigns. This garnered enough attention that he actually got a contract with the Rams which led to a year in NFL Europe where he, wouldn't you know it, led that league in yards and td's which turned into a 3rd string role on a real NFL roster behind Tony Banks and Steve Bono. Now pay attention here because this is critical for the discussion moving forward.* The next season Warner was still there but Banks and Bono weren't. They'd been made expendable by keeping Warner and the signing of Trent Greene. When Green went down Warner was next man up and you know the rest.
*We see you using the word "luck" often in trying to frame opportunity, especially as it regards Josh's career to this point. What you are badly missing is that the mini-bio above was chock full of things that were not in the least bit lucky. Undrafted from a smaller school with only a wave and a smile of opportunity out of the gate he went to the AFL and excelled. He went to NFLe and excelled. He made the roster and in one year went from 3rd string to next man up on a big league team. It was only then, at that point, one could argue he had any "luck" when the starter went down in preseason.
Which leads us to contrast how you view luck and Josh. As already mentioned he came from a major school in a major conference and got drafted. Much better start than the outliers you like to drag into such conversations.
Josh did have a small window to be next man up in 2018 but that didn't happen.
In 2019 instead of solidifying his hold as NMU he was traded to the Jags so they could keep Mason Rudolph and Devlin Hodges
So it would have seemed a golden opportunity to come in and take the helm over rookie 6th rounder Gardner Minshew. He didn't and was in fact waived at season's end.
In 2020 we see Josh back in Pittsburgh as 3rd string behind Ben and Rudolph.
Then we're with the Browns and as far as I can tell was never really in a NMU situation behind Brissett and Mond before being waived and picked up by the Lions practice squad.
So here we are with the Titans and really the only legit shot at real playing time since '18.
I don't know if you golf but there's a phrase, "never up, never in". It means regardless of how well you do anything else if you don't hit the ball hard enough the putt isn't going in the hole. If Josh had been able to keep his status as a legit 1st option (or beat out a rookie 6th rounder) behind the starters all this time he'd have almost certainly gotten this "chance" you endlessly mention. He didn't so he hasn't. That isn't "luck"...it's other players beating him out for NMU position.
FWIW I've been exceedingly unimpressed with Willis to this point so I hope Josh has his feces together. With Tannehill out and what Willis has shown us it seems more than a little likely Dobbs is going to get this "chance".
