Talk about putting lipstick on a pig.
Yes, OC'ing for the Patriots with Belichek and Tom Brady is VERY relevant. It proves he's one of the best in the business which led him to getting hired at Penn State. Also, if he wasn't good, he wouldn't have been hired in the first place. Adam Gase has nothing to do with O'Brien...whataboutisms are a very poor defense to make a point. The Patriots offense was 2nd in the NFL in total offense the year O'Brien was their OC. The NFL is often considered the highest level of football coaching, and O'Brien was able to lead the Patriots offense to the second most productive offensive in the NFL. If your only retort to his time with the Patriots is "Adam Gase", well, that's just poor on your part.
Hackenburg and McGloin. One was a 5 star QB who he recruited to scandal ridden program (proving he can recruit), the other was a walk on. Last I checked, I didn't realize O'Brien was responsible for what players did after they left his program. That's like saying CPJ is a poor coach because Justin Thomas and Josh Nesbitt couldn't cut it in the NFL. How many 'Bama QBs have failed in the NFL after they leave Saban? Plenty. Does that reflect on Saban? NO! The fact that both were developed into NFL QBs (even though he did not get to fully coach Hackenburg) shows that he can develop talent...something MUCH needed at GT. McGloin being the best example as he was a walk on that put up BIG numbers in his one season under O'Brien, and that season was with walk ons and freshmen playing a lot of minutes. From Wikipedia:
On November 17, 2012, in the course of a 395 yard, four-touchdown effort over Illinois, he surpassed Daryll Clark's career record for touchdown passes (45) in Penn State history,[8] Clark's single-season record of 3,003 passing yards,[9] and Anthony Morelli's single-season record of 234 completions.[10] He finished the season leading the Big Ten with a school-record 270 completions, 446 attempts, 3,271 yards and 24 touchdowns.[11] McGloin earned Honorable Mention All-Big Ten honors and was the 2012 Burlsworth Trophy winner, given by the Rotary Club of Springdale, Arkansas to the most outstanding college football player who began his career as a walk-on.
Don't know about you, but any coach that can do that with a walk on is an outstanding coach...it makes you wonder what Hackenburg would have done if he had all 4 years with O'Brien. But none of that matters because they didn't do anything in the NFL?! LOL...okay.
Texans. This is gonna be fun. You want to do "whataboutisms"? Let's play it: Nick Saban (15 NFL wins), Urban Meyer (2 NFL wins), Bobby Petrino (3 NFL wins), and Matt Rhule (11 NFL wins). O'Brien has more NFL wins than ALL of them COMBINED! Saban and Meyer are considered two of the best college coaches of all time. Petrino is considered one of the best offensive minds in modern college football. Matt Rhule was considered a top college coach, and will have major programs lining up to hire him if/when he gets fired. Yet poor O'Brien was able to have a better NFL career than all of them (54 NFL wins vs their 31 COMBINED wins). You don't do that if you are not a good coach.
What does it matter that O'Brien went 0-4 and got fired his last season with the Texans? Does it change the fact that the previous two seasons he won 10 games and 11 games? Does it change the fact that he made the playoffs 4 of his 7 seasons? Does it change the fact that he came in first in the division 4 times, and 2nd one time? NO...because, again, facts are inconvenient to your point. The fact is, O'Brien had a better NFL career than a LOT of current and former NFL coaches. O'Brien didn't get fired for going 0-4 to start his last season there, he got fired because he was a control freak that lost the locker room, and made horrible trades.
Alabama. These are the OFEIs of the OCs that preceded O'Brien:
Steve Sarkisian (2019-2020). 2019 OFEI: #2 - 2020 OFEI: #1
Mike Locksley (2018). 2018 OFEI: #2
Brian Daboll (2017). 2017 OFEI: #8
Lane F'ing Kiffin! (2014-2016). 2014 OFEI: #4 - 2015 OFEI: #20 - 2016 OFEI: #8
In 2021, O'Brien's offense had the #2 OFEI, in 2022 the #4 OFEI so far this season. Do you really need me to analyze those numbers? I'm pretty sure O'Briens work speaks for itself there.
How's all that for nuance? Honestly, I'm REALLY glad we had this discussion because now after all of this research, I think O'Brien is a LOT better coach than I gave him credit for...and I already thought he was a very good coach before this discussion. In fact, he's probably now my #2 candidate over Jeff Lebby and just below Jamey Chadwell.
