My understanding is the Rams could use a #1, #2, #5 or #6 on him. They traded their 7th already, and #3 or 4 are conditionally traded to the Eagles, so can't be used or traded elsewhere until that is resolved. There's no way I'd want them to use a #1 or 2 on him. Besides the red flags, he's missed all the OTAs and most of the offseason conditioning program, so is going to be behind the 4 OL the Rams already drafted. IF the Rams are unhappy after seeing one of the kids they already drafted up close, maybe a 5th or 6th - otherwise drafting him would also cost the Rams to waste one of their picks from the earlier draft.
I'm doubtful the Rams pull the trigger on him though, unless he looked so good in the workout that I'm sure he would be taken before the Rams would.
