Moore has played himself squarely onto the bubble.
I know that we have differing thoughts to some extent on Moore, QB12, but what we can probably agree on is that he's a backup player for the most part who hopefully won't see much action unless injuries occur.
One thing I would disagree with though is your assessment that he "has played himself squarely on the bubble."
By many posters accts here, he had a very fine game #1. I'll give you that he did not look as good as hoped in game #2, and saw limited time in game #3.
I respect your different opinion on a specific player, I think that will happen all the time, but what I would question is whether we even have enough of a negative sample size to judge that "he's played himself squarely on the bubble."
And if you did choose to cut him by this assessment, who would your chosen player be to replace him? Dennard? He saw his first action yesterday, has been hurt and is a rookie. That isn't going to happen as a replacement.
Cole? He may very well make the team, but even if he did replace Moore--they would simply flip flop positions from CB4 and CB5. Plus I think that a guy like Moore's versatility has made him pretty close to a lock the whole time, although I realize some would disagree. I really think it's between someone like Cole and Dennard, with Cole having the upper hand right now.
Allen? He surely didn't look good at all, and wouldn't offer much/if any of an upgrade.
To sum it up, I think that you may be correct in stating that Moore's game #2 was not good, but I don't think we have enough to go on + a real lack of potential replacements for a bottom roster backup CB at this point. In other words, I don't know if I'd agree that he's played himself that far on the bubble, even if he didn't do as well as we'd have liked.
Only time will sort this one out. You could be right though.
