I have to disagree with you a bit here. Even Solomon Willcotts was able to spot the several times today when receivers were running open, or had settled into a vacant area, and EJ straight up missed them.
Either (1) EJ is being told just to scan a certain portion of the field, for whatever reason, or (2) he just cannot read an NFL field, or worse, (3) both. In the latter case, we should move on immediately, because the staff knows for sure that their QB is inadequate and don't trust him to improve. In the case of #2, this may be something that a QB could improve (unfortunately for us fans) IN TIME, if someone can settle him down. And in the case of #1, either the staff should be fired because that offensive philosophy is not going to be productive in the NFL, or they know they have an inferior talent at QB and have to put the training wheels on (again, here, if that's the case, we should just move on). None of these options is very heartening for a team that, by all appearances, should have been able to beat the Chargers and the Texans with even average QB play.
In my opinion, the BEST case scenario is that EJ is showing the coaches in practice that he CAN scan the field and make the right reads, but is just too rattled when the real bullets are flying to do it when it matters. It goes without saying that that is not something you should take any solace in, given that we have been told that "this is our time," and management has chosen EJ as their hill to die on.
Man, this has been a long couple of decades...
