LaFell was a good signing, but I would not hang anything on the fact that they drafted a seventh round developmental player who is likely to land on the practice squad if with the team at all.
Halapio and Stork are not premier talents by any stretch of the imagination, and neither is a lock to make the final roster in my opinion.
The Patriots failure was adding JG with #62, that pick was not necessary, in my opinion JG will not be the heir apparent to Brady, and will not be a starting QB at the NFL level, we used #62 on a career backup. We could have added a first round talent in a draft this deep at #62 and JG was not a first round talent.
