Saffold stayed healthy as a guard. Noteboom lasted - what - barely more than a full game? Didn't he get hurt and go back in, during his second start at guard?
And then... out with a shoulder during a gam, and before the next game, out with a groin? Something like that... and I'm admittedly disinterested to the point of not looking it up.
Noreboom is a good person, talented football player, and the answer to his perpetual pulls, tweaks, and strains may possibly lie partially in his conditioning regimen. The Achilles, groin, and hammy injuries for the Rams keep piling up....
Nonetheless. if that's the case, he's not getting the help he needs here. And whether or not that's the case, he's not dependable to the point of being a useful pice to the Rams. Time to cut the losses before they accrue any further.
