Sorry man, I don't see driving the lane as flopping. Neither do many in the NBA, Doc Rivers said he respects how often he gets to the line because he's strong enough to do it.
That's the truth of it. Any player that can drive the lane at ease gets to the line a lot...Kobe in his prime, Jordan, Bron...you can look at the numbers yourself.
If it was so easy then why don't more players do it? Not everyone has Harden's first step or his handles.
Rockets fans don't mind it because he's always driving to the lane which gets him fouled
