Heath isn't on Lazard's level blocking, but he's feisty, willing, and has had some good blocks this year. Some felt Lazard's blocking was a bit overrated. I'm not sure I'd go that far.
Either way, you need WRs that are willing to block, not take plays off.

Sims also has potential -- he's not a bad athlete for the position, and as a backup is fine. If nothing else he can play ST. Packers brought him in as one of their 30 pre-draft visits, and his Baylor film wasn't bad. If he were coming out this year he'd be drafted, the TE class is Bowers and basically nobody else until Day 3.

Future is very bright for this team if majority of these guys develop.
