My concern with your comparison, and frankly, the reason I'm willing to be more lenient with Monken's early failures at Army is related to the respective programs. Monken took over an Army program that had 2 winning seasons in the previous 20. In fact, the 4 wins in Monken's first year were tied for the 3rd most wins that Army had in a season for the previous 17 years and the most they'd had since 4 years prior. Army was one of the worst FBS programs in the country when Monken took over.
Contrast that to Collins, who took over a program at Georgia Tech that won 7 games the year prior and had a winning record in conference play. Make no mistake, GT was not a world beater in 2018, but the team was competitive in conference play. More concerning is that this is a pattern with Collins. Temple won 10 games for back-to-back years prior to Collins. In Collins' first year at Temple, he won 7, then 8 the next. The easy response there is that Temple may have lost some key players and that hurt Collins' record. But that begs the question, why hire the guy who hasn't won anything of note as a head coach and either (1) failed to respond to player departures, or (2) did less with the same players? The most likely answer is that Collins' is a good salesman, but that doesn't change the fact that he hasn't done much of anything as a head coach.
Now, you'll want to point out our 5 win season in 2017, but again, we were competitive in conference play and lost 4 games by a combined 12 points. Contrast that with 2019, when we only had 2 single-digit losses, one of those to Citadel.
TLDR: There is no way that CGC is at more of a disadvantage than Monken was his first two years at Army. Army was likely one of the 5 worst FBS programs in the country at the time.
