Cardinals have a lot more problems than just their receiving corps.
And the Suns PG problem is an issue but if the Suns paid Booker the max to be a Harden type facilitator too then this will be his opportunity to do just that.
We saw last year that trying to make Booker a Harden type facilitator not only doesn't work at point guard, but also majorly detracts from Booker's performance overall, wears him down and gets him hurt.
