Nope, thats wrong, check their career stats. Rooney has outscored Defoe more then vice versa when comes to seasons bests. Though its jsut marginal and mainly similar level, rooney has had seasons where he scored 14 and 16 in the league, while Defoe has had 12 as best. So yeah, right now having 1 goal more then Rooney, a tally that can change any minute, doesnt mean much or make him a more consistent scorer then him. Even if he is a more natural poacher and scorer then Rooney.
P.S Sorry Sabsab, spare my nuts
