You are taking Haliburton and not signing Payton (unless you want 4 point guards, not including undrafted guys we may want to look at).
This makes you better .... when? By what degree?
Better immediately by having a PG who can actually make a 3 pointer.
Elf shot 20% on 1.5 3's a game. That's horrific. Usually if you shoot so few, the ones you do take are wide open, so your % is decent even if you are a poor 3-point shooter. 20%?
Elf made 14 3-pointers the whole year (46 game played). Only 49 FTA's @ 57% FT. That's why he's a backup PG, and spot starter.
Franc made 44 3's in 57 games at a very weak 32% clip.
Was our starter for nearly half the season.
Franc actually made his FT's (86%) but took just 59 in 57 games.
Jr. Smith made just 16's 3's in 34 games at a 29% rate.
So our 3 PG's tallied a combined 74 made 3's. Awful.
When Franc is your best PG outside shooter ... well, you got troubles.
So Ty makes us better. Provides a threat with the ball on the perimeter. Which is especially useful since Mitch and Julius are paint players. Opps can't just go under the screen on PnR's. More driving lanes for Randle and others. Open the court. Get 3 points for a shot now and then.
Re-sign Elf if you can. And then either move Franc to SG or move one of Franc/Jr. Smith, who is quite the enigma. Pretty simple stuff really.
A backcourt shooter would help a lot.
