Welcome to the board! Great post, I agree with virtually all of the points you make. The Suns can't afford to play with inexperienced PG's yet again for an entire season. Last year happened partially because Bledsoe asked out. They had all of last season, the draft, and all of free agency to find someone to man that position and all they've done is add some 2nd round fringe NBA talent to the other fringe NBA talent they have as PG's currently. 4 G-Leaguer's don't equal 1 NBA player.
Going into training camp and starting the season without anyone other than Harrison, Canaan, Okobo, and Melton will only point to the incompetence of this front office in how they consistently fail to build a balanced roster. It's bad for the coaches that have been hired and puts them in an uphill battle trying to push players into unfamiliar positions to get the most of the roster as a whole. It's not just the coaches who suffer without a real NBA PG though, it's also the other players on the court when it comes to looking to someone to initiate plays. This is the first time we've lacked a PG but it's not the first time McD has given a rookie head coach a 15 man roster that is missing an NBA level talent at a key position. How he expects them to cover for his mismatched rosters though is the real issue. He's been the constant in the last 3 coaching staff's that have failed here, 4 if you count Triano.
I agree with your premise to a point, Poop Head.
In my opinion, Earl Watson was such an awful head coach that I don't think he would have succeeded even with a roster of the strength of the Golden State Warriors, Houston Rockets or Boston Celtics. While his Kumbayah approach might have made for a nice player/coach buffer and player-relationship-builder and glorified cheerleader as an assistant, when it comes to strategic decision-making, both in games and in preparation for games, Watson didn't have anywhere near the intelligence needed even to come close to competing or keeping up with other head coaches in the NBA. (Sadly, I believe that Torey Lovullo is the MLB equivalent of Earl Watson in that respect, which is why I believe he is far better suited to being an MLB bench coach than an MLB manager.) Earl Watson really never had any business being a head coach at any level, let alone the NBA. Where Ryan McDonough lost me as a GM was when he retained Watson as the permanent head coach without much due diligence to try to bring in someone, anyone, more capable of the job. In my opinion, McDonough should have been fired right on the spot for that.
With respect to Jeff Hornacek, as his tenure with the Knicks confirmed after his tenure with the Suns, he is just way too nice and soft to instill any measure of discipline and accountability at the NBA level. He could never get through to the ego of the NBA player, and as a result, he was destined to fail even if there were no holes at any position, unless every single rotation player bought into the team and his system 100%. Highly unlikely with the mentality of millennials. There will always be an ego or two on an NBA team that needs to be kept in check.
Now in terms of Jay Triano, I don't think he is a particularly good coach, but I do believe he wouldn't have been so ineffective, and his teams wouldn't have appeared to be so awful, had he not had the gaping hole at point guard last year.
Most significant, however, where I am very much on your page is that with Igor Kokoskov, making him start without a competent starting level NBA point guard would be setting him up to fail, especially where his offensive system depends on smart decision making, ball movement and synchronicity among players.
As I said in my first post, in order for this season to be anything positive, regardless of record, this team desperately needs a point guard of a better level than what we have on the roster.
