I'd use your priority on him. Bradley is a 5-category player.
He hits for average (.321 last year)
He hits for power (2 HRs today)
He steals bases (17 last year)
He bats after Dave Roberts (good for RBIs)
He bats before Shawn Green (good for Rs)
Players like this tend to be underrated because they don't dominate in any one category. But a guy who's solid in all five is very valuable.
If your league is not a 5x5 league, he's also got good plate discipline which can help you in BB, K, OBP, OPS. He's really just a great all-around player with big upside.
