I suppose you can always have, or want to have, more talent at any given position. And, the ever present injury bug always plays a role. That said, here in year 5, I've seen some of the same things happen year to year....some more, some less. As such I lean towards coaching overall. After all this time I wouldn't call the OL dominant in any year, as a complete unit. Maybe they were competitive for most of one year - or this game or that game, but I can't call them dominant, or consistent. Unfortunately, I can say the same thing for the secondary. And there are few games (mostly last year) where I'd even say they were good. Consistency of performance over multiple years, where players come and go, for me, land in the lap of the position coach and overall coordinator. Regretably, some of this takes time for US to see - but I don't give a HC, at this level, the same about of time to reach certain conclusions. Again, not at this level!!!
