As the Broncos continue to turn over each and every stone in search of a potential quarterback to compete with Mark Sanchez and Trevor Siemian, here’s a name that hasn’t been mentioned: Rams quarterback Nick Foles.

On one hand, Foles already has earned a $6 million roster bonus for 2016, and his $1.75 million base salary for the coming year is fully guaranteed. On the other hand, there’s a sense that Foles has been tabbed as the odd man out, with Case Keenum, Sean Mannion, and whoever the Rams draft filling out the primary three spots on the depth chart for the first year back in L.A.

One source with knowledge of the dynamics already has predicted that Foles likely will be gone by the start of training camp, and that he definitely will not be on the team before Week One.

So why haven’t the Rams already moved on? For starters, the $6 million roster bonus was fully guaranteed as of last year. The only extra obligation arising from keeping Foles into March 2016 came from the base salary. If Foles is traded, the base salary goes with him.

The financial circumstances could make Foles attractive as a trade candidate. At a time, for example, when the Broncos unsuccessfully are squeezing 49ers quarterback Colin Kaepernick to take only $7 million this year, the Broncos could get Foles for exactly 25 percent of that amount.

Yes, the deal comes with $4.5 million in incentives. But if Foles does whatever he needs to do to earn those amounts, that’s presumably good news for his new team.

The bigger problem comes from 2017, when Foles’ salary shoots to $10.75 million. So it would be a one-year arrangement under the current deal.

Another problem comes from the fact that Foles simply wasn’t very good last year. Which is likely one of the reasons the Broncos haven’t kicked tires on the possibility of acquiring him.

From the Rams’ perspective, it’s likely that they’ll squat on Foles unless and until they draft a quarterback later this month. Once that happens, with maybe a free-falling Jared Goff or Paxton Lynch becoming the next potential Roman Gabriel, John Hadl, Pat Haden, Vince Ferragamo, or Jim Everett, Foles will be adding a new city to a travel itinerary that has taken him from Philly to St. Louis to L.A. in the last 13 months.
