Let's examine the candidates:
Rodgers has gushed about Adams' "humongous upside" and "incredible" athleticism, adding in January that the former Fresno State star possesses the "swagger of a No. 1 receiver." Randall Cobb lines up in the slot nearly 90 percent of the time, which leaves Adams as the obvious choice to step into Nelson's role on the outside.
2. Ty Montgomery, 2015 third-round pick: Billed as a "bigger Cobb" by Packers scout Sam Seale, Montgomery is a bit of a running back/wide receiver hybrid at 6-foot-0 and 216 pounds with strong run-after-catch ability. He quickly emerged as a coaching staff favorite, with Mike McCarthy citing the "ton of explosion" in a "strong, very powerful, obviously gifted" player.
The Milwaukee Journal Sentinel views Montgomery as the favorite to emerge as the No. 3 receiver behind Cobb and Adams. "I feel like I can do anything in this offense," Montgomery said after Nelson's injury on Sunday. "I don't want to sound like 'Next man up, get him out of there.' That's what I'm trying to get at. If that's the case, yeah, I'm ready. I can do whatever they need me to do. I'll do my part."
3. Jeff Janis, 2014 seventh-round pick: A "SPARQ" darling as one of the most athletically gifted receivers in a loaded 2014 draft class, Janis is not only the biggest but also the fastest of the greenhorn Green Bay wideouts. Although Janis replaced Nelson in Sunday's game, he has drawn mixed reviews for inconsistent camp work. Wide receivers coach Alex Van Pelt conceded last month that Janis remains a developmental project. If Montgomery stumbles, Janis will be next in line for an audition.
4. Jared Abbrederis, Myles White, Larry Pinkard, Ed Williams: A fifth-round pick last year, Abbrederis missed his rookie season with a torn ACL and has been sidelined with a concussion since early in training camp. The Packers view him as a future option in the slot. White never made it off the practice squad last season after catching nine passes across seven games in 2013. Pinkard and Williams are battling for roster spots.
5. James Jones, Giants and Jarrett Boykin, Panthers: Neither Jones nor Boykin is assured of a roster spot with their respective teams. If either is jettisoned at final cuts early next month, a return to Green Bay makes sense. Jones corralled a career-high 14 touchdown passes from Rodgers in 2012. Boykin was heralded as a breakout candidate by McCarthy last summer, before Adams' emergence pushed him off the roster. Both veterans know the offense and have the trust of Rodgers.
