Maybe this year (mostly because Poole may not even be on the floor because of positional, defensive, and comfort considerations), but it’s heading that way. JB said he was trying to get Poole back in the game late, noting that the moment wasn’t too big for him. Poole is what you want in that situation - he wants it and has the multiple tools.
Poole is already a better ball-handler than Matthews, can already shoot better off the dribble than MAAR and Simpson, etc. And for all the talk about hitting singles vs homeruns, he’s making better decisions than Matthews in particular lately. For instance, he’s gone 3 games and 31+ minutes without a TO. He’s hit 12 FTs in a row (I’m not sure if any even touched the rim) and is a 77% shooter on the year. His assist numbers are still low but he’s taking on more PnR and playmaking responsibilities and has looked the part.
Like I said, it may not happen this year because of defense and seniority/comfort level, but that definitely seems like the not so distant future.
