From what I can tell, Hernandez creates matchup problems for secondaries because the average Linebacker cannot cover him. This means a team has to use a DB to cover him if they dont want to get burned.The inevitable consequence is that guys like Branch will get less attention from the defense. Welker wont enjoy any benefit from this as teams likely feel he is too dangerous to leave alone.so the end result: Top WR(welker) takes top DB/corner. Top TE takes next best DB/corner (most likely) and #2 WR (Branch) gets the #3 cover guy Whether that is a DB. Most likely this opens up for Brady to spread the ball evenly with good results no matter where Brady goes.It is likely that only 3 or 4 teams in the NFL that have the Depth and the personell to deal with these matchup problems. The Saints had the same issue when they brought in Reggie Bush. He did more to help the passing game than he did the run game, and it would appear that Sproles and jimmy Graham will accomplish the same there.It will take a year or two for defenses to adjust, but it is clear that Hernandez helps the pats offense by more than just his own numbers.
Theyve already adjusted, it started last year when the Jets decided to just drop 6-7 DBs on the field and play in man coverage, rush 4 drop back 7. Bills did it with some relative success, the Raiders tried to do it.The biggest advantage the Pats have is that their #4 option (branch) is the only one that doesnt create a missmatch. Almost no one in the league can cover Welker, you cant bump him on the line - because he isnt on the line. No one in the league can cover Gronk, because hes 6'6" 265 and is quick and fast. Very few people in the league can cover Hernandez he'll outpace most LBs and will jump over most DBs. Its just a machine of an offense and when its performing Woodhead and Branch will be the recipient of some easily exploitable situations.
