It's coming from my common sense. It's not a 100% statement but if you have better talent at WR, logic tells me they get open more often than bad WRs. Trust in your WRs allows QBs to anticipate throws quicker in their decision making.
Example: Justin had a quicker release time with DJ last year than with Tyler Scott. He trusted him to be where he was supposed to be and catch the ball so he didn't have to wait until he got open, he could anticipate. Now if you're first read is throwing a deep route obviously he will hold the ball longer but it's a general statement.
Im sure there are some next generation stats that show that but it's ok if you disagree with me . I'm not trying to plant a flag with that comment it's just part of a conversation. I could be wrong.
Another thing, I don't think their taking OL at 9 but I watched a video with some journalists discussed the OL and I now thinks it's very possible in in a trade back. They were talking about Jenkins and his injury history. Plus this is his last year in contract. So if Poles doesn't want to pay him, he may draft his replacement now and have him starting next year. That makes sense to me .
