No peewee team will be able to sign your player since peewee cannot sign players with any XP. Best to advertise your player in the marketplace and more importantly the players need teams forum. Or PM owners of LB devoid 14 level cap teams. You may just want to stay on the team until you find a new home since its hard to find a home for a level 5 guy mid-season. If he was level 4 he could easily get on a 4 level cap team.
Or if you have the flex, PM support and ask to buy the team since it went cpu midseason on you! They will probably charge you about 300 flex or so for the remainder of the season. You guys are 3-3, and can still make a decent run in the playoffs if you can coordinate.
