I have followed some of the better experts in these and rarely have I seen them predict more than one player a team selects and it's usually in the 1st round. Why because once the 1st round and the more obvious picks are taken teams react to players selected or not selected which changes their direction and or plan going many times with their 2nd or 3rd option.
Trades often turn the tide as well early on. I acually find predicting these trades to me more exciting. While I do like discussing what our priorities are and the positions we will be looking at like the list of potential players who may be available when we select than simply cornering it down to one player in each round.
Picking 1 out of 7 rounds correct doesn't appear to be much mastering of a science to me.What's the point?
