good points overall but here are some pointers from my perspective
1- Lincoln did improve the OU offense indeed , but it has become stale the last 2 years and many defenses found it out. Note the disaster against LSU , and the losses to KSU twice and other games which OU barely won . They should have lost the West Virginia game in norman ( managed only 14 points or so ) and it was all blamed on poor rattler. OU almost lost to tulane and to nebraska in Norman . needless to mention the defense under grinch was a disaster. OU should have lost to the horns if not for divine intervention and a crazy few palys by Caleb. Will see how he does with the offense at USC , albeit the big 12 defenses are a tad better than the pac 12 .
2- if lincoln reaches 9 wins in the regular season then he has certainly elevated and he could have a good run. The defense and the lack of physicality of his OU teams are hard to forget however since he esssentially took the same staff from Norman to LA.
3- Not sure why you think Sark will fail here at texas. Last year was not good for sure, but interesting to note you think he has no chance in austin given all the talent.
4- Lincoln is a great recruiter of elite offensive weapons ( Qbs , Wrs . RB). that am sure of . But am not sure how the defense will stand up to Notre Dame , Utah , and maybe Oregon . UCLA and Stanford will be a test .
