Lets put it another way. Comparing the unequal talent hoarded by the 6 or 7 (take your pick) top college programs to the NFL system. Even with equalizing talent fans were tired of the Pats being in so many SB's and yes it was affecting ratings. It was great for Pats fans (like me) but not so good for most of the other teams/fans in the NFL. However it was a lot of factors contributing to the Pats dominance not talent alone.
I submit Bama and a few other programs usually have such a huge talent advantage it's impossible for most teams to effectively compete with them. Those lessor teams are really beat before taking the field. That's not true in the NFL because on any given Sunday division leaders are beaten by so called lessor teams. There's only a very marginal talent gap between most NFL teams as opposed to what's happened in college football imo. Even the BEST NFL teams hardly ever go undefeated unlike what happens with college teams. The last NFL team to go undefeated and win the SB was Dolphins 48 years ago in 1972! Let that sink in as opposed to college ball. As a matter of fact the Dolphins are the ONLY NFL team to have ever accomplished that feat.
Bottom line I believe programs like Bama are destroying college football and it's only getting worse with the portal. I had to turn off the sound during the Bama-OSU as I was getting nauseous listen to the non stop gushing about Little Nick and Bama! I'm not the only college football fan absolutely worn out with seeing mostly the same teams year after year playing in the NC! It does reach the point where many fans simply no longer care to watch it. We have so called experts that make big money running college football and those people had better figure out how to start making it a lot more competive imo. If not there's going to less viewers each year.
Many experts are already picking Bama, Clemson, OSU and OK to make this year playoffs!
While not completely the same, this is the same thing people said about a handful of programs in the 60s, 70s, and 80s.
