hernandez is below average at every position he lines up at.
he is too small for a tight end(easy cover for a db, cant block at all), and too slow for a reciever(easy cover). the scheme makes him good.
Gronk on the otherhand, presents a multitude of problems. but again, the ravens have the two best ballhawking defensive players possibly ever in Ray Ray and Mr Reed.
everyone forgets just how terrible the Pats defense is...
