I really didn't like the fact that the Bills waited (and waited and waited) to finally address the TE position. The idea has been floated that the Bills really weren't terribly interested in TE once their top guys were off the board. I was one of those who railed against waiting until the 3rd round (I never even considered the Bills might wait until much later.) to pick a TE precisely for that reason.
With that said, I can see why the team picked Fine. The reason is named Langston Walker. Of the 14 games I broke down (recorder took a dump the Denver and Jags games) Walker had help on 48 of the 403 (11.9%) of pass plays. Help is defined by the RB/HB/TE helping Walker block his defender--not picking up some other defender while Walker blocked someone else. Sometimes the RB/HB/TE chipped and went out into the flat and other times he just stayed in the backfield and helped with pass protection. In either case there was one less receiving option available for the first couple of seconds of the play for the QB to get the ball to.
My guess is that the Bills will continue to give Walker some degree of help about 10% of pass plays. Of the TEs available at the end of the 4th (End of the fourth?! Ugh!) there were basically pass catcher and blockers but none who could do both. The Bills went with a blocker, just the kind of guy who can help Walker and then drift into the flat if Walker seems to have things under control. Fine is exactly that kind of guy.
As for Viti, the Bills didn't have a guy who could get up a 4 yard head of steam and blow a LB out of the hole last year. Here's the thing, though. A FB like Viti is at his best when he can crash through the C/G gap and clear a hole for the guy behind him. The Bills don't run straight ahead due to Fowler's inability to hold the point of attack--let alone generate a push. When the Bills ran 'up the middle' last season they really didn't do it in the traditional sense. Instead, the G and T from one side of the line crashed down and sealed off one side of the lane (with Fowler attempting to be the pivot point). The outer wall of the lane was generally formed by the TE and a pulling G. Occasionally, WRs were employed as well. Needless to say, this didn't work at all when the Bills faced 3rd or 4th and short. Could the Bills see Viti as the type of guy who can slam into the C/G grap and create enough wiggle room for Lynch to squeeze in behind him? I don't think it would be a staple of the offense but a guy like Viti might really help the Bills in those short yardage situations. If so, it's another reason to like Viti...
