2 star potential could be a starter potential guy... that isn't hat bad. (in best case scenario, a 2 star guy will be a star potential guy, worst case, you'll get a 6th man potential guy)
personally, i'd put the second guy one position up. 19 year olds are players who have lost a precious year of training in my eyes...
but that is a personal reason. if you don't intend to train them up to a decent lvl (30 to 40 k salary if youa re talking about a C, then a decent lvl is 50k salary) then you might as well go with the 19 year old guy.
it all depends on what you want to do with them
