Let's not get crazy. Monk could literally fly. Herro's killing it and is far better than I thought he'd be at this moment, but he's nowhere near as athletic at Monk.
That being said, I can easily see the comparisons. Both have a lightning quick release while only needing the smallest sliver of space to get their shot off. They can light you up for 12 straight points in a matter of a few possessions if you let them loose and they heat up from deep. They both have an incredibly strong midrange game in a modern era that doesn't seem to utilize it all that much. They both could/should be starters but also be incredibly valuable off the bench as instant offense as the 6th man (which is where I always felt Herro belonged). Yes, they're VERY similar. But if Herro could sky like Monk, he'd be a top 10 pick.
