re: Why is it that Jeremy Hill would break a long one damn near every week and LF...

It's a good question in the OP. And it needs to be pointed out that Hill missed an entire season of ball and yet was doing this in '12.

I don't think Jeremy has Leonard's top end speed but he has better vision.

Two key points:
1) Our OL played like garbage until the UF game.
2) LF's vision is getting better - he's simply runing more mature. Enjoy.
