I would roll the dice on the defenseman. But we also need centers so who knows. Does patterson have better than 2nd line center potential? I know going into the year liljegren had top pair potential and that's more valuable so I'd gamble on that. We need to hit on a center or defeseman in this draft guess it doesn't matter which.
Well as a comparison, Petterson has notably better point totals than Hank had in his draft year or draft +1 year for the same team, while being a better skater, 2 inches taller and heavier than hank was at the same age...and is regarded the best playmaker in the draft outside the guys we definitely won't get.
Personally, I'd be happy with either as both have question marks but very very high upsides. But Pettersson is the better player at present
