MLG is very high wear and high maintenance equipment. So much so that many airlines have complete overhaul shops dedicated to just the gear.
Not only the movable pieces, but the trunnions take a beating as well. On an otherwise pristine appearing aircraft it is amazing to see how worn and beat up the gear can be.
Inspectors will quickly determine the cause.

The gear collapse in this one appears to be trunnion failure.

Yes, but the Cardig trunion failure was caused by the 3.68G landing which was in turn caused by not going around from an unstable approach.
I don't think that the problem is that the 737s landing gear is weak but the beatings they are occaisionally given in some parts of the world is immense.
Any aircraft's MLG will fail if you land hard enough on it.

Reading the report, the high flare was a contributing factor.
The root cause was an internal oil leak in the shimmy damper, after which the holes in the swiss cheese lined up. The MLG detached as designed to prevent wing penetration, spar damage and a serious consequent fire risk.
Full marks to all involved for the good outcome, it seems that trying to grease it on is a bad idea on the 737.
