It's difficult to forget how fans flocked to Tim Tebow when he joined the Denver Broncos in 2010.
Fans swamped Denver's training camp and open practices, wearing Tebow jerseys, just itching to get a glance of the former Florida quarterback.
Chicago rookie quarterback Mitch Trubisky isn't quite as polarizing as Tebow was, but head coach John Fox can see some similarities between the two — not in playing style, but in their marketability.
Fox, who coached Tebow with the Broncos, is now at the helm for the Bears and has noticed how fans are starting to fall for Trubisky.
"[The] first time we threw Tim Tebow out in Denver, [it] was pretty similar," Fox said, referencing how fans showed up to see Trubisky play.
When Tebow arrived in Denver, he was pushing Kyle Orton for the starting job. A similar situation seems to be unfolding in Chicago.
Before Chicago drafted Trubisky with the No. 2 overall pick in the 2017 NFL Draft, it signed former Tampa Bay quarterback Mike Glennon to a three-year, $45 million deal.
In their 24-17 loss to Denver in Week 1 of the NFL preseason, the Bears watched Glennon complete 2-of-8 passes for 20 yards and an interception. Trubisky, on the other hand, connected on 18-of-25 passes for 166 yards and a touchdown.
Glennon was signed with the intention he'd be the starter. But a strong campaign from Trubisky could change that in a hurry.
The third quarterback on Chicago's roster is veteran Mark Sanchez, who knows far too well about the hype Tebow brought with him to the football field when Tebow was with the New York Jets.
