On one of the kickoffs, Puyol was in on the tackle (he is not a very large kid) and for a moment appeared to be a bit shaken up. What would plan c have been if he did get injured.
I don't want to get into a pissing match, on an issue that is more irritating than substantial (which I stated far earlier in this thread), especially with someone who is so deeply entrenched in P's camp as you seem to be but there could have been far more (not necessarily better) options available if three months ago P considered the possibility of a football player getting injured during the season.
