[cobirds] Lincoln’s Sparrow, yes or no? Photos .Arapahoe county location, Aurora

This most looks like it is a Lincoln's Sparrow to me, as best I can tell in these obstructed photos. The streaking on the breast looks too delicate to me for a Song Sparrow.
Mostly I'm questioning because it came up as rare for Coal Creek Arena in Aurora today.
I appreciate your thoughts before I submit to eBird!!
Much thanks!!!
