Given that he CRs the flop a LOT and follows through on the turn a LOT, his range before he river bet is obviously quite wide. So now he is looking at that river and having to decide if its a good card for him to fire his final barrell at. Obv its very "level" dependant but Im thinking that he knows that river card looks gross to most of our range, so hes prob following through on his bluffs with a high frequency and thus we need to call here.
