I would rather take a shot on the intelligent ball distributor types who don't have great raw tools, the Brady and Brees types, because you can take one of them every year until you hit while also building the rest of your roster. There's quite a few QBs in this draft that go outside that top group and have a mix of different strengths. Take one that your OC feels a nice vibe with, or that you really like his competitive drive, and then take another one the next year and year after that until you get one you can believe in.
These feast/famine high end lottery ticket types, for every Allen there are a bunch of failures or guys who cap out where they can't put a team over the top in the biggest games or even develop the mental side enough to succeed at the NFL level. This ain't college. Defenses are fucking smart, they are well prepared, they will take away what you do well at some point even if you're a great runner which Richardson certainly is. So hard pass for me.
