People need to look at the numbers behind "holding the ball the longest"
If you go by the column labeled TT (time to throw) and look at 2016
https://nextgenstats.nfl.com/stats/passing/2016/all
TT is defined as: Time to Throw measures the average amount of time elapsed from the time of snap to throw on every pass attempt for a passer (sacks excluded).
RW is ranked no 20 -- so below middle
Now here is the kicker. Go look at no 15 -- Flacco -- time 2.56 / pass
Go look at no 31 - Kirk Cousing -- 2.8
The difference is 0. 34
So when RW runs around ONE TIME for 3 extra seconds that means that for the next 10 plays he increased his average with 0.3 seconds. He does this at least 3 times PER GAME. So on average his running around is really what makes people think he holds on to the ball to long each time. It also ignores that at times we are totally fine with a sack over the throwing it away and getting it picked off.
Sure he gets into bad spots at times because of what he can do but you have to pick. You can either be fine with it or if you don't want it then remember that you don't get the scrambling around and then throwing a miracle throw to Richardsson to win the 49ers game either...... which do you prefer?
