I will still and will always say it was a serious reach...
If you buy a car worth 15k dollars for 25k dollars and it runs great and runs for 10 years... you still paid 10k to much for it.
You are correct in saying that Frederick might could have been picked a little later, but that isn't a good analogy, IMO.
If you buy a car worth 15K, then it will never be worth more than 15K. Ever. At best you end up with a long lasting car that originally was worth 15K. Even at peak performance, it is still a 15K car.
You would need to say that you buy a car that some thought was a Kia worth 15K and you paid 25K... and then everyone realized that it really wasn't a Kia at all, but was instead a BMW that was really worth 100,000K. It would have to be a car that could compete with the best.
Of course, using car value at all as an analogy for players in the NFL draft is ill advised, period.
What you had was a guy that was looked at as a late first round player because of the position he played and because of how well he played at Wisconsin. Then, after the combine and his slow 40 time, his stock dropped into what realistically was the second round.
As with most good football players who run poorly at the combine, Frederick's stock began to climb up some because team's start paying a lot of attention to what they did in college as you get further from the madness of the combine and closer to the draft.
Frederick was the best center in the draft by a wide margin. Those typically don't slide further than the mid to late second round, so I don't think it could be realistically said that he would last any longer than that. Wisconsin consistently puts out O Linemen that perform exceptionally well in the NFL, and he had played well for a long time at UW.
The strength of the 2013 draft was along the OL and teams were grabbing them up at a torrid pace. When NY took Justin Pugh at 19 and Chicago took Kyle Long at 20 (the 8th OL already taken), you know those guys are going early and often.
Dallas saw nobody worth the 16th pick to them, so they took the best trade back deal offered and gave #16 to SF, who took Reid.
At pick #31 where they traded to, the only interior OL that they really liked there was Frederick, who Bill Callahan really, really liked a lot. Johnathan Cyprien and Matt Elam were there but Garrett has been insistent on building the trenches, so I don't think they were ever realistic candidates to be taken over Frederick.
There were plenty of rumors that said that Baltimore wanted Frederick at #32, and I don't find that an outrageous theory. They needed a C and Frederick was clearly the best in that draft. Plus, he is a Raven type of guy.
The only decent players that were taken between Frederick and our pick in the second of Escobar was Gio Bernard, Kawaan Short, and Kiko Alonso. It was a pretty weak draft and there wasn't really a whole lot of guys that Dallas could have taken that would have been a better fit at a bigger need than Frederick.
The point is, regardless of where draft guru's had Frederick ranked - and they only had him ranked below the first round because he ran a poor 40 - he was most assuredly the best guy they could have taken. Particularly with a coach and a fan base that wants help in the trenches more than any where else.
You can't logically say that he would have been there in the mid-second, and he was the best at a position of need for Dallas. It was the right pick, mock draft value be damned.
Of course that is without even bringing up that they got a free 3rd round pick and got a very good WR there who is also a starter in his second season and leading the team in receiving TD's.
With the particularly potent ability of 20/20 hindsight, the trade and the pick of Frederick can't be looked at as anything other than a home run for Dallas.
