His draft position is relevant to his perceived value at the time of the draft and what had happened since will change that perception.
To ignore where he was drafted is to ignore the grade teams put in him before he sat in NE for 3 years aside from playing a game and a half.
Every team evaluated him pre draft and adjust their evaluation as time goes by. They didn't not know who he was prior to him playing a game and a half.
We are talking about two completely separate things. Though neither will be affected by the price we paid for the player in draft currency.
One is value (or perceived value), while the other is cost.
Yes, part of his potential value for a team will derive from their earlier notes during the draft evaluation process. But where he was actually drafted won't affect that. If a team had a 2nd round grade on him, they might feel better about that assessment. But if a team had a 4th round grade on him, they aren't going to bump him up based on the Patriots taking him earlier. Just because the Broncos spent a 1st on Tim Tebow does NOT mean all teams will value him similarly, or grade him a bit higher since he was drafted so high.
Also bear in mind that we got KILLED by some "experts" for the Jimmy pick. Meanwhile some reports say some teams had him ahead of Derek Carr, and potentially a 1st rounder. Different values, different teams, but where BB selects him won't shift his value to those teams. If a team had a 2nd round grade on him, it wouldn't fluctuate if he got drafted in the 1st or 3rd. His grade is independent of what we paid.
So that is value. And yes, draft tape and notes will matter, actual draft position won't.
What also won't is price, specifically what we paid for him in draft currency.
Saying we spent a 2nd round pick on him is irrelevant in negotiations. It's not like Cleveland is thinking about giving us a 3rd, and we can whine, "But we paid a 2nd," then they change their offer. Nobody gives a **** when it comes to what pick we used to select him. Just because we overpaid or underpaid for a guy doesn't alter the value to the other side.
And that's why it doesn't matter where he got drafted. The value isn't affected by where he was drafted, and neither is the price.
Think about it this way. The Patriots had a 3rd round grade on Tom Brady. But they didn't draft him until the 6th round. What is his value? A 3rd like he was rated, or a 6th because that's what they actually paid?
Or do they value him like a 1st overall based on his play?
