Diggs is the best, Ravens have a better tight end, other than that I think it is pretty even. This may be an extreme example, but look what Brady did in NE with average at best receivers. This was largely because of his talent, but also becauee of how they used those receivers; route combinations, Brady's ability to make all of the throws.
Here, Lamar can't make all of the throws, he has the arm for sure, but his confidence or the time he has in the pocket keep him from even attempting some of those throws. Troy said it best the other night. Some patterns have to be thrown on time, before the receiver even makes his cut, his move. We rarely see Lamar make that type of throw..
Now, Allen was this way his first 2 years as well, and he made the move so far this year. Can Lamar?
