In the top 10 you never draft for need, you always go BPA. This is not NBA and there would be enough playing time for all of these prospects, even including centers.
I personally think that if you, for example, believe that Cooley is very likely to become the next J. Hughes, you draft him and roll Hughes-Hischier-Cooley as your center group and if push comes to shove, you pull Johansen-Jones type of swap. Some people will counter that with saying that you can get Seth Jones level of d-man in Jiricek and Nemec but in my opinion, the risk of both of them is much higher than risk related to Seth Jones at the moment of Johansen trade (when he already had several NHL seasons of experience).
Not saying that Cooley is the pick here but drafting for need in top 10 ends up with Zachas and Kotkaniemis.
