I changed the DB schema - suggest you rethink yours. Anytime there are column names FOO1 FOO2 FOO3 that's a red flag of an awkward schema, however SQL Schema theory is beyond the scope of this reply.

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1142225

use strict;
use warnings;
use DBI;

$_ = 'QB Carson Palmer RB Chris Ivory RB Eddie Lacy WR A.J. Green WR J
+ohn Brown WR Davante Adams TE Martellus Bennett FLEX Jeremy Hill DST 
+Panthers';

my $dbfilename = 'db.1142225';
unlink $dbfilename;
my $db = DBI->connect_cached("dbi:SQLite(RaiseError=>1):$dbfilename");
$db->do('create table players (team text, position text, player text)'
+);

my %dups = /\b([A-Z]{2,})\b(?=.*\b(\1)\b)/g; # insert counts if needed
for my $position (keys %dups)
  {
  my $n = 1;
  s/\b$position\K\b/$n++/ge;
  }

# make hash

my %db = /\b([A-Z]{2,}\d*) (.*?)(?= [A-Z]{2}|$)/g;
#use Data::Dump 'pp'; pp \%db;

# remove team (this is a guess)

my $team = delete $db{'DST'} or die "no team";

for my $pos (keys %db)
  {
  $db->do('insert into players values (?, ?, ?)', {}, $team, $pos, $db
+{$pos});
  }

Here's the DB as dumped by sqlite db.1142225 .dump

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE players (team text, position text, player text);
INSERT INTO "players" VALUES('Panthers','QB','Carson Palmer');
INSERT INTO "players" VALUES('Panthers','TE','Martellus Bennett');
INSERT INTO "players" VALUES('Panthers','WR2','John Brown');
INSERT INTO "players" VALUES('Panthers','RB1','Chris Ivory');
INSERT INTO "players" VALUES('Panthers','FLEX','Jeremy Hill');
INSERT INTO "players" VALUES('Panthers','WR3','Davante Adams');
INSERT INTO "players" VALUES('Panthers','WR1','A.J. Green');
INSERT INTO "players" VALUES('Panthers','RB2','Eddie Lacy');
COMMIT;

DB Hint: come up with the several ways you will query the DB and that might help your DB schema (sample query: "get all RB". This is slightly awkward with this schema, how is it with the RB1 RB2 column name schema? )
