Calling Wlad unskilled is like saying James TOney and Sam Peters are only chubby, no matter how the division is, you cannot win so dominantly against everybody without a lot of talent; The guy's style is "boring by our standards but he's a Kronk style of boxer, you set the tone with the jab and you get your big hand next, all being patient. IF he can win without using all the rest, why would he?
If I would be him, I would do all the same probably, accurate, effective with lesser dangers, we might not like it, sure, but indeed, that's extremely effective, I think that it only takes a damn good fighter to win a match almost only using his jab.
