There are many good resources at your fingertips with a single google search but the player analyses are mostly useless if you are patriots fan, because most "experts" have no idea what the patriots are looking for any particular player or at a particular position. I think that most of us can agree that they like the following types of players: captains, players who play for BB's good friends, players who can play multiple positions and player who have top 3 cone times. Other than that, who really knows.
A good rule of thumb is if you like a player and want the patriots to draft him, cross him off your list. This is why the lead up to the draft is always more exciting and enjoyable than the draft itself. On occasion, BB will draft a "name player" that you lust after and when that occurs, it is glorious.
