I actually was one of the guys wondering if the Pats would use Tebow as an H-back. Again, looking at the measurables (the only thing we don't have is bench press) Tebow is pretty credible there. Everything "objective" says he could physically play that position.
Compared to Hernandez, Tebow was the same height, 10 pounds lighter, and had a faster short shuttle, three cone, 10 and 20 yard dash splits, vertical jump, and broad jump. He even has bigger hands. Hernandez has better arm length, 40 dash, and bench press (Tebow n/a). Obviously Tebow runs pass routes like a clown and hasn't blocked anybody in his life, but the Pats have carried Bequette for two years, and Chris Barker and DJ Williams were permanent fixtures on the inactive list. The Pats could have carried a project this season if they wanted to.
Given that the Pats have moved QBs to WR (Edelman) and DEs to TE (Silvestro) and played a bunch of LBs at TE, I don't think there was anything on the Pats end stopping them from moving him apart from Tebow's desire to play QB.
Harrison, meanwhile, isn't too far behind Hernandez, as he tested at 17 reps and 231 lbs. Plus he's got freakishly long 35" arms (that's better than a lot of OTs) and jumping/explosive ability so you'd think IF the Pats were going to take a WR and make him a Hernandez (or an Antonio Gates) it would be Harrison, since he's also a project with lots of practice squad eligibility. Not LaFell.
It's a great offensive role waiting for someone to claim it. Hope the Pats find somebody, even if it means LaFell making me look like an idiot.
