1) In light of BB's stated goal of having the entire roster, down to the 53rd man, be stronger than every other team's, I perceive that there are a lot of roster spots that are currently weakly-staffed at a lot of different positions.
2) I perceive that this draft class in particular, compared to 2009 and what I've seen so far about 2011, offers a lot of prospects who could upgrade a lot of those weak positions all the way through the bottom of the roster.
3) Based on an average of the prospect rankings across several sites (which, admittedly, at best only vaguely reflect the reality of how the 32 teams actually have the prospects ranked), I perceive that there should be strong prospects to upgrade the Pats weakest positions available all the way through the 5th round (though not necessarily in rounds 6 and 7, which appear to be the usual crapshoot). I also perceive, based on those same rankings and on what I've seen of the prospects, that there are NOT a lot of them who are likely to be taken in the 1st and 2nd rounds who necessarily fit the Pats at their particular positions of greatest weakness. However, there appear to be a lot of very talented players there who might really help other teams.
Therefore, my first guess, given the situation as I perceive it, is that the Pats are likely to receive a significant number of trade offers for their current first three picks. Based on the "traditional" trade-value chart, mathematically those offers would necessarily include at least one second round pick either for 2010 or 2011, in addition to a 2010 3rd, 4th or 5th round pick. My second guess is that the Pats accept at least one of those offers and thereby expand the number of picks they have in the mid-rounds (without necessarily "losing" a 2010 second-rounder, but just taking a later one). The "interesting" part is trying to project what teams might make those offers, what those offers might be and what BB might do with them.
I certainly recognize that others on this board will disagree vigorously with my perceptions. And I accept that BB's perceptions, the only ones that really count, are very likely to differ greatly from ALL of ours. But that IS, of course, the "fascinating" part of following the Pats draft - trying to match BB's perceptions. I feel no shame in being "wrong" relative to what BB ends up doing because the differences always reveal just a little more about how BB perceives things and about how he thinks. This, for me, is one of the main points of the exercise.
