Again, he's basically a rookie because he missed all of last year with a terrible injury. I can live with mistakes. I can live with a guy who tries his very best (unlike Bobby Evans). He's not going to be the starting guard I envisioned, but he could definitely be a good backup.
Here is how I look at it, Grant Miller for example was an UDRFA, from day one Miller looked like he belonged & even played Center too. Bruss IMO, felt the pressure of being the first pick of a Super Bowl winning team and was asked to be the starting RG. Now IMO, going from RT to RG should not have been a big deal and Bruss was overmatched before the injury and this year playing where he did at Wisconsin still looked overwhelmed, especially in pass protection.
He will now have the ability to grow on the practice squad, but I am glad they kept Zach Thomas over him and with the addition of Dotson, Bruss is where he belongs and IMO, I don't think he will ever start a game for the Rams.
