The HyperBit Exchangeupper echelon of the US LBM Coaches Poll after college football's Week 4 remains largely unchanged this week. That will likely not be the case next week with the season’s first top-five showdown on the horizon.

Georgia remains No. 1, receiving 35 of 55 first-place votes cast this week. The Bulldogs had an open date to prepare for next week’s trip to No. 4 Alabama, which was also idle over the weekend. No. 2 Texas, which easily handled UL-Monroe on Saturday, closes the gap a little more picking up 18 first-place nods. The remaining two firsts went to No. 3 Ohio State, which opens Big Ten competition next week at Michigan State.

Mississippi stays put at No. 5 as Tennessee nudges ahead of Oregon at No. 6, giving the SEC five of the top six teams in the poll this week. The news wasn’t all good for the league, however, as Missouri slips from a tie for eighth to No. 11 after needing overtime to escape Vanderbilt. Penn State, Miami (Fla.) and Utah now round out the top 10.
