i played back the cowboys game, specifically to look at austin...
as to the drops, i agree with a poster above... the first "drop" would have been a one-hander... the second he probably could have done a better job of securing it (caught it briefly before being dislodged by the DB (carr?)... i can cut him some slack for those... the third drop in the end zone was i thought the most catchable...
he did also make some very good catches... one down the left sideline where he outjumped & took the ball away from the DB... another where he went in the air on a pass thrown high & behind him where he made a nice play on the ball...
as to the theory that he sort of got lucky because KC missed a lot of tackles... his career average is 20+ YPC... that is on just 33 receptions, so it is admittedly a very small sample... last season he had 20+ YPC on just 13 receptions, which was the most for a cowboy WR since alvin harper (24+ YPC) in nearly 15 years... but the point being, he has flashed great promise in limited opportunity... the cowboys would, imo, be crazy to not greatly expand that opportunity...
they do have a lot invested in roy williams, as has been noted upthread, but austin playing an expanded role isn't mutually exclusive with williams remaining a starter... as has also been noted, crayton looks like a better fit as the WR3, where he can pick on nickle coverage... it is true that anybody can have a good game, but his performance was exceptional (best in DAL history, 15th best for a WR in NFL history)... he looks like the best DAL WR, & they are sorely lacking for explosive plays (especially with felix jones out, which seems to be a regular occurrence)...
some observations on austin... KC did miss some tackles, but he flashes elusiveness and open field running skills, so looks like he is capable of making DBs miss, even against better teams... what most impressed me was his unusual combination of size, quickness & speed... he is a listed 6'3" 215... he has explosive initial quickness, and gets to full speed in about two-three steps... once up to speed, he has long strides & is rarely caught from behind (obviously, with that kind of career average... when looking at the game sunday, even smaller players weren't gaining on him once he was in the clear)...
some WRs have great initial quickness (seemingly more important than raw track speed), some have down the field speed (almost a pejorative, need to get going)... austin has both, which isn't common even for a smaller WR...
he reminds me somewhat of brandon marshall (bigger at 6'4" 230) in his physical tools, skills & game... even to the unfortunately high frequency of drops...
it just seems to make too much sense for austin to get more playing time to not happen... having an explosive playmaker & deep threat would help the run game (forcing the safeties to play honest), as well as clear out the middle for witten, both which would help romo, and he could be instrumental in making the cowboys offense more balanced & stronger overall...
i don't agree with the posters that seem to think it was flukey & he will disappear back to where he came from... obviously he may never have a 250 yard game again... but there is LOTS of room to do less than that... & still be highly productive, and play a key role for the cowboys & fantasy owners down the stretch...
for longer time frames & dynasty purposes, they signed him to a one year contract in the off-season... they could have a big decision to make regarding him in the off-season... if i were the cowboys, i would want to have a better idea of what exactly they have in him (i don't think they really knew based on his limited action previously)... and essentially a no brainer decision when that course of action looks like it would also be consistent with doing what puts them in the best position to win NOW...
* incredibly (to me), in four leagues i just checked on, he ranges from #8 WR - #16 WR, DESPITE very mediocre games weeks 2-3-4... if they use him anything remotely like they did on sunday (in terms of targets), imo, he can put up top 20 WR numbers (with possible top 10-15 upside), GOING FORWARD this season...
