1.) Paying market value is not "overpaying" just because you claim it is. If you personally slot Bodden at, say #10 CB in the NFL, paying #10 CB money is not overpaying. I, personally, slot Bodden as #1 CB on the Patriots and, since I'm not worried about the money in this uncapped year, I've got no problem if the team has to pay him more for his services than they would have in other seasons. The necessity for doing so could have been avoided by either paying Samuel, by Keeping Hobbs and paying him (assuming he didn't suffer the same sort of injury in New England, of course), or by drafting more successfully when targeting cornerbacks since 2005.
2.) BB's discipline with respect to paying players has cost the team several top players who might have contributed to additional playoff and/or Super Bowl victories.
3.) The uncapped year allows you to frontload contracts so as to avoid issues with the salary cap should it return in the future. Just for an example, one could give Bodden a 3 year deal with payouts of 12, 6 and 3 million dollars per season, which would accomplish the $7 million goal and not have significant salary implications moving forward. I'm not saying the Patriots need to pay Bodden any particular number. I'm saying that the number needs to be all but irrelevant at this point.
