He is left on an Island A LOT! He will miss a few times, when he is completely alone out there. There was an excellent analysis done last year near the end of the season, and Tyron is NOT given a ton of help consistently. We might be playing with multiple tight ends a lot more, but on pass plays, they aren't helping him out as much as Free's side, and haven't since he's been here.
Considering that, I think Tyron played significantly better last year than he was given credit for, and is somewhat under-rated already, despite as young as he is.
Leary is helping compared to Livings etc...
Imagine if Tyron had a pro-bowl guard to play beside? Waters will teach him how to be mean - this is a huge benefit of having him added to the team. Toughness he brings to the young guys.
