Even in the Caro-Kan, white has aggresive options, which Hydra might choose.

For example Anti Caro-Kan (2.c4) , opening up the position, or advance variation
(3.e5) with either Nc3 and g4 (the usual choice) or 4.c4 (as Morozevich plays).

It would not be safe for Adams to play these positions I think.
