get_stats() function Dummy values result in NaN

[reedpayton23]

The following has two dummy stats, which cause later fields to be off. And the empty dummies result in a NaN (not a number)

<tr><th class="left " data-stat="season" scope="row">1 season</th><td class="center iz" data-stat="age"></td><td class="left " data-stat="team_id"><a href="https://www.basketball-reference.com/teams/IND/">IND</a></td><td class="left " data-stat="lg_id">NBA</td><td class="center iz" data-stat="pos"></td><td class="right " data-stat="g">65</td><td class="right " data-stat="mp">894</td><td class="right " data-stat="per">9.5</td><td class="right " data-stat="ts_pct">.507</td><td class="right " data-stat="fg3a_per_fga_pct">.427</td><td class="right " data-stat="fta_per_fga_pct">.133</td><td class="right " data-stat="orb_pct">2.3</td><td class="right " data-stat="drb_pct">6.3</td><td class="right " data-stat="trb_pct">4.3</td>
<td class="right " data-stat="ast_pct">20.7</td><td class="right " data-stat="stl_pct">1.4</td><td class="right " data-stat="blk_pct">0.9</td><td class="right " data-stat="tov_pct">17.2</td><td class="right " data-stat="usg_pct">19.2</td><td class="right iz" data-stat="DUMMY"></td><td class="right " data-stat="ows">-0.2</td><td class="right " data-stat="dws">0.5</td><td class="right " data-stat="ws">0.3</td><td class="right " data-stat="ws_per_48">.016</td><td class="right iz" data-stat="DUMMY"></td><td class="right " data-stat="obpm">-2.4</td><td class="right " data-stat="dbpm">-1.2</td><td class="right " data-stat="bpm">-3.7</td><td class="right " data-stat="vorp">-0.4</td></tr>

For example, (This specific example is for Aaron Brooks)

['2016-17', 32.0, 'IND', 'NBA', 'PG', 65.0, 894.0, 9.5, 0.507, 0.427, 0.133, 2.3, 6.3, 4.3, 20.7, 1.4, 0.9, 17.2, 19.2, nan, -0.2, 0.5, 0.3, 0.016, nan, -2.4, -1.2, -3.7, -0.4]

This happens for every single player, and the dummy may be in different locations.
