Daddy tried really hard last year but he's pretty weak on the boards and didn't generate anything on the powerplay. Mostly useless for majority of the games.
I wouldn't say he tried hard. There is something endearing about Dadonov, but his second effort is terrible. His version of battling was standing 4 feet off of a scrum and putting his stick in the mix. He makes efforts to get to loose pucks, but once he's beat (which is usually how it goes), his efforts to get it back/become an obstacle are pretty weak.
I do think he can be much better for Vegas... he is certainly capable of contributing on the PP with the right set-up, and that was totally lacking for him in Ottawa. I have very little doubt that he can score 20 or 25 + and be a positive player.... he just really wasnt that in Ottawa. The most frustrating part about that, for me, was that he wasnt doing the little things that almost everyone else on our team does. When you have Brady, Brown, Batherson, Norris, Stutzle, Paul, Watson, Bishop, and even White digging in, battling, giving a second, third and fourth effort, and generally being more productive than Dadonov at the same time, it makes his play stand out more.
That said, he went from attempting about 4.5 shots per game in Florida to just under 3 in Ottawa... he went from producing .2 powerplay pts/game to .018... his on-ice shooting percentage went from 11.5% to 8.4% and his on-ice goals per game went from 1.37 to .70. If he can split the difference on those totals (3.75 SA/G, .1pts/G on PP, on-ice 1 goal/G, oiSH% of 9.9%), he would be around 25 goals and 20 assists and I think that's a reasonable expectation for him to hit. If he finds the right fit, I could see him pushing 30 goals and 60 points. It is hard for me to imagine him being worse than last year, and his pace was still approx 20 goals and 30pts.
