The patriots are doing something fundamentally different in their approach. Let me support that with some statistics.
Right now there are 25 players opting out, 6 on the pats (source: https://www.nfl.com/news/list-of-nfl-players-to-opt-out-of-2020-season). If all players opt out with equal probability, there is a 1/32 chance each is on the pats. The total number of players on the pats opting out would be binomially distributed, with 25 coin flips, and success with probability 1/32 (https://en.wikipedia.org/wiki/Binomial_distribution). The probability of 6 or more successes (i.e., players opting out) is p<1*10e-4 (https://stattrek.com/online-calculator/binomial.aspx). Therefore having this many opt-outs on the pats randomly occurring would happen 1 in 10,000 times.
Also come on, it's the pats.
