I think it's safe to say he won't be thrown into the deep end. We have Rubio, Tyler Johnson, Javon Carter, and probably Ty Jerome ahead of him on the depth chart so we'll be able to take our time with him. I actually liked how Okobo was handled last season for the most part, until Melton got hurt. We threw Melton into the thick of it right away because he proved to be a capable defender but Okobo spent most of his time in the G-League or playing limited minutes, if any at all, on the main roster. Unlike other players, he had a fully guaranteed contract so it wasn't a case of him being on a Two-Way deal with limited time available on the main roster. I think we'll see something similar with Lecque, playing in the G-League a lot and only spot minutes on the main roster until March or so. At that point his minutes might be expanded some depending on if the Suns are vying for a playoff spot or not.
We'll see what happens but having someone from Golden State's player development side and Monty gives me hope. Monty worked in the Spurs front office before returning to the bench in Philly. Coaching in Philadelphia should have taught him a lot about player development also since they just went through "The Process".
We also have Harper signed to a Two-Way deal and he's much more of PG than Lecque is but I think Lecque's future is more as a combo guard so I don't see them getting in each other's way much, if at all.
