I have no problem with this trade.
Obviously the guard is not rated to be that great or he would be gone.
You are looking at second round talent from this point on and with Bell and Wharton inked there is no reason to draft a back up guard right now.
Hightower is solid and we don't know if Rey is going to be suspended for his bar fight and Moch and Muckelroy are hyped by the staff but we have not seen them yet.
Bottom line, I will take the extra picks instead of over reaching for a lineman.
