That is a real good analysis, but trading down and drafting J.J. Watt isn't a good move, imo. Watt isn't explosive or athletic enough, imo. If the Patriots like Cameron Jordan that much and are willing to trade up to get him, then, if you go DE, you should consider going that route. Look at late rising junior Jerod Mayo, an All Pro. They took him at 10. If they are willing to move to 9 and take Jordan and you want a DE, then, that should make you pause.
Jordan is the more explosive player, but I would remind people in the war room that my guy Smith blocked him (especially in the running game/as a 19 year old junior), is 20 years old and has the upside that Jordan really doesn't have. Smith replaces the weakest player on the offensive line immediately and gives you a fighting chance at LT if Free walks or gets hurt. Plus, you get the best offensive linemen in the draft, imo. You don't have to sweat out the second round.
You have some good players, and I like Sherrod. However, supply and demand will most likely have him drafted in round 1. Those OTs are going to all rise. If you pick a real impact player at 9, you are still looking at a really good OL or CB option in round 2. If Danny Watkins falls to 40, he could replace Kyle Kosier on most NFL teams.
I'd just stay at 9 and draft Tyron Smith who has Pro Bowl potential and has the potential to be a dominate player in pass protection and run blocking. Dallas needs difference makers up front, and Smith has difference maker written all over him. Felix Jones would really benefit from his athleticism in the running game. Jason Witten would get to go out for passes more. Romo and the passing game benefits. For Felix Jones, Power O (see his 73 yard TD in wildcard game), sweeps, toss right, screens, and stretches would open up for Jones to the right. (See Colombo block 2 guys on Jones' 33 yard TD against the Bengals in 2008). Colombo can't block anyone, anymore. He has no pop. He can't move. He's done.
Plus, Tyron Smith can pull along the line and do the blocking that Davis can't do on a consistent basis, especially on the goal-line. Smith could anchor your line for the next 12 years. Hudson Houck is a USC guy, so I have a glimmer of hope.
There really is no excuse for Mark Colombo to be penciled in as a starter. If that truly is the case, it's going to be a long, long, long year. He should have been replaced in the 2009 draft, and I can't believe the Cowboys would even consider it. It's foolish. The Packers dynasty has already been launched. The Giants, Eagles, and Commanders are going to address their offensive lines in this draft. The Eagles and Giants need OTs. Dallas' starters will average 33 next year on that line. It could get ugly. I'll say it will get ugly if they stand pat. Can you imagine the heat that organization will take if they don't do something? You can start at 9 by taking the best OT in the draft.
Number 9 is going to be a significantly better player than Watt, and I'd take that guy.
If the Cowboys get to round 2 and the top OT prospects are gone, they are going to pay big time on the field, imo.
If Doug Free goes down (assuming he is resigned), this team is done. Smith gives you a fighting chance at LT his rookie year. The RT has been done since his last major leg injury. Colombo was never a dominant player to begin with, and he has given up many QB hits.
I like Sherrod, because he can play LT. However, he's not as talented as Smith, and giving up Smith for J.J. Watt isn't going to cut it for me. That is just my opinion.
You would be better off just staying at 9. That should be an impact player for the Cowboys. Just let round 2 fall to you. That is going to be a really good player, too. OL, CB, WR (Perhaps the DE from Ohio State)
