Well, from my perspective there is second guessing and there is nonsense. Did you look at the situation Jenkins caught the ball in? Where was he going to dribble to exactly?
You make a general statement that “1.5 seconds is often enough to do a lot of stuff of stuff”, how about some specific examples? More to the point, I cited the circumstances Jenkins caught the ball in, with defenders within arms length of him, and ask you where do you think he could have gone on THAT PLAY? Because that is the play you guys are speculating on, and tacitly criticizing him for, not a generic hypothetical “often enough”!
So, with all due respect to the “pure speculation“, IMO, it is pure nonsense, and that’s all it is, my opinion. Take it for what it’s worth to you.
