I think Dantonio is a fine coach, but I don't really understand his inclusion on these sorts of lists over someone like, say...Jimbo Fisher? I try not to weigh national championships too heavily when thinking about coaching ability/ranking, because not every coach is fortunate enough to have A+ resources. But, Fisher generally has a very strong argument over someone like Dantonio. Dantonio finally got MSU to the upper echelon in 2010, and he is hailed as having four 11 win seasons in five years. However, since MSU's rise in 2010 (the same year Fisher took over at FSU), Fisher actually has the BETTER winning percentage (84% vs 76%.) Fisher has the better overall win percentage (84% vs 66%), better bowl record (4-1 vs. 5-4), more conference championships, despite less time coaching (3 ACC vs. 2 B1G)
Of course, Fisher has the National Championship on his resume that Dantonio doesn't. He also has a 29 game winning streak (2012-2014) and he is the man who ended the seven year SEC reign of terror by beating Auburn. He is also 1-0 vs. Urban Meyer.
While Dantonio is regarded as a defensive master, it's actually Fisher's Seminoles that have been ranked higher in total defense 3 out of 5 years (2010, 2011, 2012). And, if one wants to tout Dantonio as a masterful program builder, it's not like Fisher doesn't have that on his resume too. He took over a Florida State team that went 30-20 from 2006-2009. (60%) He instantly took a 7-6 team to 10-4, and has since won 84% of his games.
