Not sure if I'm too enthused by the idea. Sure, he's a great player, and could be an all-star again. However, he's signed till 27, makes a ton of money (57M in 26-27), and has played 57, 60, 40, 50 games over the last 4 years.
His scoring average, after a career high of 31.3 in 20-21 has dipped to 23.2 over the last 2 years (though his % is still high).
By contrast, Huerter is 5 years younger, makes a third of money, and his %ages are similar to Beal. Given the older age and the missed games, I'm not sure it's much of an upgrade (if at all), for three times the cost.
