They are being groomed. Just not to your visual satisfaction. Their team is not this year's team, not next year's team, but more than likely, the following year's team. A LONG TERM plan used on QBs NOT drafted in the top of the first round, but rather those that are undrafted and those that have played 8-9 college games and sucked at baseball and haven't played ANY organized football in 3-4 years.
And make no mistake, I'm not implying anything. I'll be as clear as I can here, noone owes you an open audition to meet your approval. Bledsoe is your QB for the next year, maybe 2. Romo is next. Henson's shift to NFLe isn't to see if he'll compete for a starter spot, but to see if he's going to get a chance to compete for a 3rd string spot.
Now, back to your whining.
