Well, that's B.S.You and I both have zero idea if Elway thinks he can make a deep run Flacco. You're assuming it but you have nothing to base it on. He But if we're going make wild assumptions as what Elway is thinking, mine is he thinks the team will be more competitive and be in better position to make the playoffs not that it's a given.
I have EVERYTHING to base it on! Every move the Broncos have made this off-season is to win now. Elway keeps saying things like Flacco is "in his prime". He clearly expects them to make the playoffs. If he didn't think they could get in the playoffs they would not have bothered to sign Flacco in the first place. That would mean they were a rebuilding team and should just start Lock and see what they have ahead of the 2020 draft when several QBs like Tua and Fromm will be available.
The goal in Denver has NEVER been to just get to 500. It has always been to get to the SB. Every move Elway has made for better or worse has been with that goal in mind.
