No, just no. John Wall is the clear choice, and Washington management has already voiced that they will be selecting him. The difference between the picks in Favors and Turner is very slim. Both of them are inter-changable 2nd and 3rd picks. John Wall is projected to go 1st on almost all draft boards, and rightfully so. Why would they select Turner just because Wall is considered the number one pick...
And even if they were going to select Turner, they'd trade the pick instead of just drafting Turner at number one, since no one is stupid enough to pass on Wall.
Wall may not have upside? That was almost laughable. There's a reason he's projected number one on every mock draft. He's projected to be very, very good.
There is no way that Cousins goes in the top 3. There are way too many question marks, and his weight is beginning to be an issue for a lot of GMs. It is also projected on a lot of mock drafts that Cousins could even fall to number seven, my team, the Detroit Pistons.
A lot of your reasoning is based on the fact that a few number ones have gone a bust. However, in no way do previous picks and results have any inclination on success from THIS draft, especially given the fact that your betting against the odds.
I may seem a little harsh, as it wasn't the intent, but there is no way that Turner goes ahead of Wall.
