I think an A+ range player is SUPPOSED to get 30ish + plays regardless of what position he plays now.
I am finding that A, A- and even guys in the B's are getting + totals in the teens and twenties.
I am also finding that my LF is picking nearly as many + plays as my CF. The CF generally has a higher RF (usually something 2.3 to 1.6) but the +'s plays are higher proportionally.
