Adam Dunn also had enormous power and a bit more overall contact which @bmags pointed out. Unless Collins is hitting 35-40+ bombs like 2004-2012 Dunn did (along with contact), then sure. But he is most likely going to walk 65-75 times which is what 2013-2014 Dunn did with about 20-25 bombs and about the same amount of contact, barring him improving on that of course.
