Nobody knows how the rookies will perform in their first season. So EVERYTHING is just either hope or pessimism. Any evaluation of their past performances in college enables evaluating these guys in comparison to each other. But there are no guarantees how they will adapt to the NFL.
So in my opinion all statements about the future can not be facts. And that's why all off season talk is basically just a time killer for us fans. I'm not saying we shouldnt do it, I mean what else do we have to talk about? But facts have nothing to do with it.
So, my guesses:
LT: short term: slight to medium deterioration, long term: this position is secured, great draft pick
LG: short term: slight improvement, Smith has a year of experience on his belt now, he'll improve
C: short term: slight deterioration, Beebe will pick up the game fast, but no improvement in the first couple of games over Biadaz, great pick in the long run
RG: same as last year, or a slight deterioration, Martin isnt getting any younger. But still, everything's fine here
RT: slight improvement, Steele should be completely healthy now
Chemistry: Who knows? But this line is very young with Martin as the father figure, should be working out. Looking very much foward to it, can't wait to see them in action! And THAT's a fact lol.
Overall: These guys need to gel, let them find their way in the first 8 games or so. Expecting good things in the second half of the season.
Edit: And even though I'd prefer a new QB under center, I do hope that Dak and this young o line will connect quickly. Some people are talking about 6 wins max, I'm still in the 10+ team. The core team is still intact and the defense will get a new design. If Dak can utilize his o line I'm not worried about making the play offs even though the first couple of games will be rough. What happens in January though will be a whole 'nother story of course! No hopes here on my part.
