Yeah, I'll bite.
I supported Costa and felt he could be an average NFL center and maybe even be slightly above. Despite repeating those expectations over and over again, there were several posters who took my words and somehow twisted them into the idea that he was going to be one of the best centers in the league, he was going to the Pro Bowl, etc.
I would suggest that there were a lot of individual posters that had hope for one or the other of that group....Costa, Kowalski, Arkin and Nagy. Generally, I think most of the Costa supporters didn't think too much of Kowalski and vice versa. I don't really remember anyone being really excited by Arkin, I would say the great majority felt he was a wasted pick especially when he couldn't be called in over Dockery.
Nagy seemed to be more of a tough guy, scrapper and unfortunately injuries just seemed to follow him. He seemed to be the kind you might have starting but you would always be looking to upgrade the spot. Despite having interest in seeing a couple of these guys pan out, I never was averse to the team signing free agents or using high draft picks to improve the OL.
After drafting Frederick, I did feel that the top 5-6 linemen on this team were Smith, Frederick, Free, Leary, Costa and Berny. The biggest question was whether the line was better with Frederick at C and Berny at G or Costa at C and Frederick at G. As it went forward in training camp, it became pretty clear that Frederick was better at C than G so everything settled in pretty quickly. I had no problem with Dallas letting Costa go as he strictly is a center and probably wouldn't ever be active on gameday as such. In fact, I posted it either here or on the Ranch in one of the threads about cap space way before he got cut. It is interesting that Costa did get picked up relatively quickly after being released. If Indy leaves him at center, I think he can compete for them.
