Hate to break it to you but I believe the Tyler Johnson trade is the closest we'll come to trading for a PG this deadline.
I know one of the talking heads said they were surprised this deal took so long to materialize because it had been something that both Miami and Phoenix had worked on since December but I don't know if I buy that. I know Tyler Johnson isn't a big name but it seems like every move the Suns make or don't make now has one "insider" saying they knew about it months ago yet they have zero proof they did. If they were truly an insider of some sort then they would have floated the rumor out there, like other deals get talked about, even if they don't happen.
