I see GPII as a hybrid of Tony Allen/Avery Bradley:
-Built like Bradley (as athletic as either one) & can play combo guard (has shaky handles like a young George Hill)
-Has Tony Allen's rebounding ability & shooting touch
-Likes to take it to the hole like pre-injury Tony Allen
-Tony Allen was 23 when he got drafted & was essentially ready to play from day 1.
You also have MCW, Elfrid Payton, Dante Exum & Marcus Smart recently getting drafted in the lotto based on potential when they couldn't shoot a lick.
Ray isn't bringing to the table anything that Patty/Tony aren't & is essentially being used as a NECESSARY emergency backup since Tony has been breaking down the past couple of season. With the departure of CoJo, PATFO needed a 3rd string point guard who was NBA ready & having been a starter on a lotto team Ray was qualified for the job.
This upcoming Summer the team needs to look for a long term defensive minded point guard because that is what the team is lacking & is necessary in a conference which sports the top 3 point god in the league: Curry, Westbrook, Cp3. (You also have CJ/Lillard, either one of whom could run circles around Tony/Patty in a playoff series).
You aren't going to get an NBA ready center with the 29th pick (Should have cap space to sign Ian or even Noah if Tim/Manu retire...there is also Hibbert
) & that defeats the purpose of winning NOW while LMA is in his prime. There is no need for a wing player when you have Kawhi/Danny starting & being backed up by Simmons/Kyle(who can't even get consistent minutes in the regular season). A combo guard would be welcomed with Manu on the verge of retiring & Tony on a decline but that is exactly what GPII is, a defensive minded combo guard.
If you look at recent history there have been a handful of wing players that have been signed from the D-League & a couple centers from the Euro league that have made a smooth transition to the NBA without costing the team a 1st rd pick. I can't think of one point guard that made the same transition, actually the Euro league point guards have been busts & the D-League point guard couldn't stick. GPII is a known commaditiy who isn't going to be drafted based on potential or being able to run the offense in the NBA, he's just going to be a game manager & energy guy/defensive stopper who will be asked to play spot minutes in the postseason ala CoJo.
