I make few comments here, but this one I couldn't let go. Your hypothetical is a fairy tale, Callahan wasn't and X and O coach. a fool to change to the west coast offense with the current talent he had. Have you lost your ability to evaluate a situation/team/season? Your question/comment shows the intellect of a 7 yr old. Open your eyes and your mind and it would be obvious that Callahan didn't have a clue even as an NFL head coach. Callahan could recruit..... (the extra periods indicate the end of BC's talent) Pelini could go 7/5 and he won't be fired. A new AD with one yr under his belt on the new job, isn't going to fire a coach with one so so yr out of six.
Let's put things in perspective. Changing offense/defense scheme, Changing conferences after 3 yrs, need to recruit differently for B1G, current players on roster at time of conference change were recruited to play in B12. Yeah, is all football, however IMHO, the B1G is a superior conference is every aspect. i consider Pelini's first two seasons in the B1G successful. The first year, he played a bowl game every week, the second yr he had some familiarity with the conference teams, but it was only the second season in the B1G, with arguably the toughest in conference schedule among the top 5 teams, yet finished with at least 9 wins. Give the staff credit for what they have accomplished. Changing conferences is a difficult task, just ask West Virginia, or TCU. West Virginia was picked by some to win the B12 in their 1st season (much like Nebraska was) and experienced the same fate as Nebraska did in the B1G. It's difficult to change conferences, play new opponents weekly and still win at least 9 or ten games is a decent accomplishment.
Does Pelini need to do better? Absolutely!!!! He's fixed his offense, no it's time for him to go back and get his defense playing like they should. I for one think this season could be very special, with all the talent on offense, and speed and talent (although young) on defense. Do you recall Peini's 1st season in Nebraska, did a great job with a defense stunk up the place the yr before, came in after callahan and did the same again. He needed to spend time on the offense to get the right coaches and players in place to accomplish his goals, he's got the offense going, now with his full attention back to the defense, I see great things, and I don't usually drink much kool-aid, and I'm not drinking it now. Just a fan of over 50 years seeing the Big Red Machine getting turned around and heading back to top ten finishes and playoff contender. GBR
