the analytics data is enlightening, Taylor has gotten about a quarter second more per snap before the pressure was upon him compared to Jones, and that is being weighed down by the Seattle game in which pass protection hit rock bottom; if we look at just the starts for both QBs, its an extremely stark difference. It also shows that Taylor is somewhat faster to abandon the pocket than Jones is, even despite enjoying improved pass protection.
the one reason I suspect Taylor may be the right QB for this particular offense, when leaving the pocket he does seem better than Jones at keeping his eyes downfield.
But a weakness in Taylors game is his quick hook on pocket passing. A good example came on his handful of deep drops over the last couple weeks. If there's a pocket, Jones steps up. Taylor rarely steps up when those edges come around at 10-12 yards, instead he bails. Its a long running problem with his game, its the one thing that separates him from being a really legit starting QB, in my opinion.
So Taylor is probably a little better when things break down.... but, he's also more likely to cause things to break down.
