Two I can think of are:
Dexter McCluster. This guy is a little maniac. He should see the ball often and with good reason. He is a playmaker. His numbers could be decent BUT>>>>> here's the catch
If Jamal Charles goes down the McCluster will become Jamal Charles 2.0. They look like twins and McCluster has 90% of the skill that Charles possesses. Dex may be better in the screen game too. A lot of upside and potential 10 pt + potential.
Next one is Aaron Hernandez. I know Gronkowski is still around, but Hernandez is just so much better. I think Hernandez will be a favorite target in the end zone too this year. He has the size and athleticism that Gronkowski could only dream of. HE HAS MADE AMAZING PLAYS IN THE END ZONE BEFORE AND THIS WON'T BE FORGOTTEN BY TOM BRADY. Gotta love his yards after the catch potential.
