2 grams per lb is I think well beyond the point of diminishing returns, and depending on goal likely past the point of any further returns.
With regard to absorption of proteins supplied as whole proteins (as opposed to for example di and tri peptides) the figures I recall seeing for measured absorption were 10-12 grams per hour maximum, as average for the subjects without any great variation between subjects. Still, obviously, a bigger person likely absorbs more than a smaller one.
At the 12 gram/hour figure, then maximum possible absorption would be 288 g. Plausibly for male lifters on average, somewhat more for the size reason.
In practice, for male lifters I generally find 300 g/day to be a reasonable useful maximum.
What would happen to the rest? Bacterial metabolism. Some of the energy would be absorbed by the body however as short chain fatty acids.
Your 200 g figure is absolutely fine.
