I ascertain if you are not interviewing your top picks then they will be likely wasted because potential is soo important a factor
True. But I think you're overlooking the key word in your own sentence: YOUR top picks. Who you interview when you have the #2 pick and who you interview when you have the #14 pick should be completely different.
If you are 6th in a league than 12 guys draft before you and you can'T inteview 12 guys AND scout once everyone else without spending a lot of money.
True again. But why spend money interviewing prospects you have almost zero chance of selecting? Resources are limited, and you have to focus your scouting points on the players that are likely to fall to you.
If you have a high draft pick, spend your scouting points on the 5-ball prospects, to make sure your high pick pays off with a quality prospect.
If you have a low draft pick, spend your scouting points on the 3- and 4-ball prospects, because the 5-ball prospects won't fall to you and you need to find a talent amongst the lesser lights. This is what I did; I knew I was picking late in the round, so I spent all my scouting points on 3-ball prospects. This turned up a 5 talent/4 potential player with the 14th pick. You've got to kiss a few frogs to find the prince, but overall it's a worthwhile investment.
