The first involves the franchise's potential relocation to Los Angeles and the other involves the team's longtime quarterback, Philip Rivers.
However, if you're asking NFL Media analyst Daniel Jeremiah to make the choice between holding onto Rivers or starting anew with Mariota, the decision is clear.
"I think that Philip Rivers is their best chance to win football games in this upcoming season and over the next few years," Jeremiah said on NFL Network's "Path to the Draft" Wednesday. "To me, this decision will come down to not only what they think Rivers has left, but how much conviction do they have in that room for Marcus Mariota. I'm talking about owner, general manager, head coach, personnel staff, coaching staff.
However, a proven commodity at quarterback in the NFL -- especially one at Rivers' level -- is hard for any team to pass up in order to explore what an unproven player can do under center.
