Not implying the pilot involved "yanked" his 737 off the ground but just saying there can be some interesting rotation techniques among different pilots in general.
Because of the increased length of the 737-900 and the A321 over previous models, I've heard that pilots who fly these aircraft types along with the shorter 737's and Airbuses have had to make a conscious effort to slow their rotation rate a bit to avoid tickling the tail.
We used to get an occasional tail strike on the 727-200 at the intersection of runway 13/31 when departing on runway 4 at LGA. Back then, no one really thought it was such a big deal. After all that's what a tail skid is meant for. Right?
