No, but I think the risk that he can play and whatever his motivations are—and there's lots of debate about intentionality—was it about getting access to certain seaports and getting access to certain gas resources that the shale revolution would allow Ukraine to go and exploit, and therefore use as a counterbalance to the influence of Moscow? There's lots of that.
All I'm mentioning is—and to answer your question, no I do not believe he is reasonable; rational, perhaps—Putin probably believes that he can get away with things in Crimea that he would not be able to get away with in other parts of the world.
