What we have seen from Keenum so far is promising. He has a nice arm and has shown off his ability to extend plays with his legs, either running for positive yardage or buying time to make a throw downfield. His weakness right now is clearly either recognizing the blitz pre snap, beating the blitz with quick passes and proper reads, or both. Securing the ball when he is hit has also shown itself to be something that he needs to work on. He tends to hold on to the ball until the very last second, which can result in both good and bad things.
Evaluating Keenum comes down to three things: a) is he better than Schaub or the best QB we have right now, b) is he good enough to be given a chance at the starting job next year, c) is he good enough to avoid drafting a QB high next year?
I think a) and b) have already been fulfilled. He's clearly offering us better QB play than what Schaub was offering. He has shown enough promise to be given a shot, if not be the frontrunner, for the starting job next year.
Where a lot of people are getting caught up is whether or not he is good enough to avoid drafting a QB high next year. People seem to have different mindsets when it comes to this. I think this is why you see a lot of people not so much expecting, but hoping to see Case play like a veteran. We see a lot of people saying "give him some time" and that's absolutely fair, but people are really just trying to determine if we can bank on this guy to be the future. People who are criticizing Case's play are trying to figure out this issue.
The way I see it, Case would have to dominate for me not to be interested in a QB high in next year's draft. It's almost not fair to him, as he is just a rookie with little experience, but it's just the reality of the situation. Vinny and ArlingtonTexan bring up good points in that there are guys who flash for a half of a season or so and then regress. We can't afford to go another season with poor QB play/poor QB options.
Right now, I think we need to look at drafting a QB high and let Case and that QB battle it out in training camp next year. I'd bet that Keenum would win that battle and probably should be given the opportunity to start the season next year at QB. Still, it would be nice to have another young option to groom or turn to if Keenum plays poorly. Worst case scenario is that both players don't have what it takes, best case scenario is that we have two strong assets at QB. Atleast in this scenario, we have some options.
