— EXTRA POINTS: TCU coach Gary Patterson has declined to close the competition between Casey Pachall and Trevone Boykin, who became the starter last year when Pachall was admitted into a substance-abuse program. It will be fairly surprising if Pachall, an NFL prospect and maybe the best quarterback in the Big 12, isn’t starting when No. 20 TCU faces No. 12 LSU on Saturday night. ... New North Carolina State Dave Doeren has yet to decide between Brandon Mitchell, a dual-threat transfer from Arkansas, and pocket-passer Pete Thomas. ... Texas Tech coach Kliff Kingsbury is probably down to starting a freshman against SMU because of an injury to presumptive No. 1 Michael Brewer. We’ll find out which one Friday night.
