1&2...it would seem to me your reading comprehension is the one that's struggling. You claim Bowden is a bit shorter than Hubbs, most on here seem to be in agreement from seeing Hubbs out (newsflash he's in shoes in public) that he's about 6'5", maybe 6'6". So if you're admitting that Bowden is a bit shorter than Hubbs, whether in shoes or barefoot he's still shorter, then you're admitting that in shoes if Hubbs is 6'5" then Bowden is probably 6'3ish". Now as I'll go on to explain, shoes are generally 1.5-2", so if you're admitting Bowden is 6'3-6'4" at best in shoes, then you're also admitting he's likely 6'1"-6'2.5" barefoot at best, which would pretty closely jive with his listed height.
Now as for shoe size, I have all along said 1.5-2", check out draft express which lists NBA combine measurements...at the combine guys are measured in shoes, and not in shoes, the difference is almost always 1.5-2"...I'll list a few for you since you apparently haven't seen that.
Jarnell Stokes without shoes 6'7" with 6'8.5"
Kevin Durant without shoes 6'9" with 6'10.5"
Nerlens Noel without shoes 6'10" with 6'11.5"
And just for clarification you said you bet he's closer to 6'5" than 6'1" barefoot, so you're claiming he's every bit of 6' 3.25" barefoot, meaning in shoes in your opinion Bowden would measure at the very least 6'5"-6'6"...sorry, but I don't see that. It's also a bit coincidental that you seemingly are trying to make a guy you've admitted to being biased about taller than he likely is.
