You seem to have some anger problems man, is everything OK?
The point of it all is that time skip power levels are far above pre-skip levels, for example, current Zoro would make pre-skip SHP run away and even forget about playing pirates again, so the BBP from 2 years ago running from Akainu but Shiryu now being stronger is not that shocking for me given what Oda has done to the power system.
Also Teach and the crew were not pissing themselves as your implying, its well established by now that Teach never takes on fights that might cause him to lose his men without him getting something in exchange, even if he ends up winning Teach has been shown not to take fights like that, that's why he didn't fight Rayleigh and Hancock because even if he would win he would still end up losing his manpower, pretty sure BBP{ if they tried they would have beat Akainu but lost a lot of men, and for what a ship?
It seems you very much are in love with the admirals but doing so at the expense of disregarding manga facts is just idiotic my guy
