Most that dislike are bitter aggys who haven't won a title since the Third Reich or finished in the top 5 since the Eisenhower Administration. Vince will be fine....2 years from now people will wonder when he learned to pass so well. He has a real good game and then a real bad game now (look at his gamelog -- his QB rating will be 90+ or around 50). He is passing much better, he messes up mostly from making bad decisions. This is much like his soph year at Texas.
Mario is a stud. I am happy for him.
I am an Aggie, and everything you say is true about A&M. And while I would like them to do better, I hold no ill will to any player from Texas, except on the specific day they play, and even then it is more a matter of hoping the Aggies play better.
That being said, your comments on Vince and where he will be in 2 years, I would remind you that a ton of people said the same thing about Michael Vick. Heck I just heard a Cowboy player on a radio show (yes I live in Dallas) actually claim if he was starting a franchise today, Vick would be his 1st pick. I hope Vince does discover how to harness all his obvious talent and make it work to his benefit in the NFL (although I wish death upon the Titans because of Bud Adams). I have just noticed that it is very rare that a player "suddenly" figures it out in the NFL. Most show either the ability day 1, or a stead progress toward "figuring it out". There was a time when QBs didn't play much in the early part of their career because the coaching knew they needed time to learn and adjust. So what Tony Romo has done the last couple of seasons was more the norm, but in today's NFL if you are drafted high you are expected to come in and almost right away produce. Vince has enjoyed a great deal of success winning games, but I think you are hard pressed to say he was a big reason for most of those wins. Heck, even Rex Grossman went to the Superbowl, and I doubt anyone thinks he is a good QB. So wins don't always tell the story with QBs, but I will say that QBs are rated more than any other position based on their teams wins and losses.
But as for the Texans and Mario Williams, I think they made the right choice. I think if you are building a team, yes it is nice to have a good QB, good RB, good WR and such, but you want to build a team that will win consistently, you need to start with the DL and OL. You work from there first, and then build the other parts. The last things I think you add are the QB and RB, not that you don't look to add them, but what good is a QB if you can't protect them, and what good is a good offense if you can't stop the opponents.
Much like baseball where if you are building a team, you should focus as WadeSmith have preached, with pitching, defense and speed. Having hitting is nice for show, and you will need it to win it all, but if you want consistent success, you need the others more. In Football you need quality play in the trenches to win consistently.
And as for Mario not being the best, 2nd best or 3rd best on his team... Give him some time. He may not be one of them yet, but I bet you he will be soon. He may never be "better" than AJ, but if I were to guess, he looks like he will be better than anyone else very soon.
