I dont know, i never had too much trouble getting linebackers,
I know you have the most interest when a position is in need on yur team, so if you go into an ofseason with less than 3 OLBs then you will have plenty of guys interested usualy
Also try in season recruiting, when i do it i never target more than 5 guys, which means i can dedicate 20 points to each of them, which all but assures that i will make it to the top 3 in thier choices, usually before the midway point of the season, then take a guess to what tehy want to hear, invite them and cross your fingers
I dont know anything about 360 though, your going to have tofigure that out
