Of course it can be. The Red Sox had Papi AND Manny and won two World Series while all the while their fans got to watch two dynamic, charismatic players who were paid handsomely. It absolutely can be both.
Manny Ramirez, huh. I guess we have different ideas about charisma. To me he was an obnoxious clown. A truly great hitter, but a clown. And a juicer. Ortiz. He was a DH. To me, that's not even a baseball player.
Seriously now, the numbers that get thrown around for Harper are around $35M/year with an opt-out after 3 years. I'll buy that, IF IT IS A TEAM OPT OUT! But he'll want a 10 year commitment from the team with a three year commitment from him. I want no part of that deal.
