Hmm, now I don't know what to believe. Tried looking it up online and found this
http://cover32.com/rams/2014/01/09/bill-obriens-tactics-similar-to-steve-spagnuoulos/ , but it doesn't really go into specifics or anything. Also this mentions it as well
http://www.kmov.com/sports/football/headlines/Spagnoulo-ripped-by-Saints-player--185458802.html and found this which kind of clarifies if true:
Other steps included taking down photos of the Greatest Show on Turf teams and failing to invite any player alums to help the coaching staff.Needless to say, this has rubbed former Ram greats that hate seeing their team going 1-15 the wrong way.
To quiet of the complaints, Spagnuolo has announced that he is creating a “Pro Bowl Wall” at Rams Park to celebrate current and former Rams that have made the Pro Bowl, which by the way is the weakest of all All-Star games and is such an honor that half the team drops out of the game every season.
If he didn't then I was wrong and just went with that rumor I guess. Wasn't that hard to believe.
