For a long time it looked the Titans were sitting in the catbird's seat for the 2017 NFL Draft. At No. 5 overall, they were the fulcrum point for quarterbacks, with the Jets, Bills, Browns, Cardinals all looming below them as possible trade partners.

There was a really good chance the Browns (or someone) would swing a deal to the fifth overall pick to land Mitchell Trubisky if he fell. Then the Bears decided to blow the whole draft up by trading up from No. 3 to No. 2 to draft the North Carolina quarterback. It was a stunning deal that caught everyone off guard.

Appearing on Sirius XM Radio, via Pro Football Talk, Titans GM Jon Robinson admitted that the Bears grabbing Trubisky basically snuffed out any chance they had of trading down from No. 5. 

"We had some calls about pick No. 5," Robinson said. "When the trade happened between San Francisco and Chicago, it kinda threw water on anything in that spot."

The logical move would have been a swap between the Browns and Titans for the No. 5 and the No. 12 pick. The compensation likely would have been the Titans' old second-round pick, No. 52, which the Browns later used on Deshone Kizer.

But the Bears surprised everyone and (over)paid the 49ers for the rights to move up one spot in the draft so they could grab Trubisky. Those surprised included coach John Fox as well as current quarterback Mike Glennon. And the 49ers

It did set off a chain reaction, of sorts, when it came to the quarterback position, because it created a shortage, which meant that teams needed to move up the board and get the quarterbacks they wanted. The Chiefs traded up to No. 10 with the Bills to grab Patrick Mahomes, while the Texans traded up to No. 12 with the Browns to grab Deshaun Watson

Three quarterbacks in a very weak quarterback class going in the top 12 is a perfect encapsulation of the economics of the NFL Draft.

It's not hard to imagine it playing out differently, though. If the Bears aren't in love with Trubisky and pass on him, then the Titans get blown up by the Browns on the phone, along with maybe even the Chiefs or the Texans. 

The Bears correctly understood that Trubisky was a valued commodity. But they might not have correctly understood how valuable the picks they gave up were, either. 

At Football Perspective, Chase Stuart has a good look at the cost of doing business for the Bears in the trade. It wasn't cheap. And don't sleep on what the 49ers did with the two picks Chicago gave up either. The No. 111 pick was given to Seattle to move from No. 31 to No. 34 (back into the first round) and acquire Rueben Foster, a steal at that position. He wasn't making it past the Saints at No. 32. 

And the No. 67 pick was traded to the Saints who moved up and took running back Alvin Kamara. They gave the 49ers a future second-round pick in exchange for that selection. The Saints' second-round pick this year was No. 42 overall. You don't have to add that into the package of picks the Bears gave up, but there is a real opportunity cost for not staying pat at No. 3. 

There was a cost for the Titans too: as a result, the Bears destroyed the draft board and eliminated Tennessee being able to move down in a trade.
