Three overall thoughts on this:
1) I don't know why anyone thinks the timing on this is crazy or suspicious or whatever. To me, this is just like basic honesty. When they were making non-committal statements, they hadn't committed yet. Now they have, so they are making these statements. I mean, Schneider came out and said exactly this almost immediately after we drafted Howell. The only reason to act surprised now is because people were pretending that he hadn't said what he said.
2) I think this indicates that our QB room is pretty final. One of my first thoughts about why there was such an immediate change in rhetoric after we brought on Howell is that Schneider still wanted to keep Drew and knew that they needed to keep the conversation open about his chances to be the starter. I don't think there was any chance Lock would have been the starter this coming year personally, but I don't think they wanted to torpedo that aspect of the conversation publicly.
I also think this means we aren't planning to draft a QB, at least not one likely to be anything other than QB3/practice squad material. Schneider already indicated he likes a BPA approach to the first half of the draft followed by filling needs in the second half. With the way QBs are expected to come off the board this year, there is no chance any QB we see is going to be BPA and with a Geno and Sam on the roster, it's also not a position of need.
3) People on this board seem to overemphasize the value of a 'QB competition' and understate the value of having decided on your guy. Look, will Howell win the starting job if Geno completely poops the bed and Sam lights it up in camp? Sure. But different QBs are, in fact, different QBs. That means if you are planning to fit your scheme to your players and not the other way around, it actually helps if you have decided which players those are going to be, especially ones who are as integral as the QB.
Grubb is going to be trying to design an NFL level offense for the first time. It's going to be beneficial for him to know which QB he's designing that system around.
