Not so much a sign of weakness from the protesting players (of which this apology DID NOT come from) as it is a growing divide between ownership and the players. Anything that continues the slow death spiral of the NFL is fine by me.
Nah - the Jags owner travelled to London, knelt on the field during the National Anthem, but was not the one who sent this letter. Jags are having the owner side with the players, while the GM takes the opposite side with this letter.
