The Anthracite League collapsed after the season, but Striegel and the Maroons were undeterred. They applied for, and received, a franchise in the NFL. This was somewhat unusual, as the team's
Minersville Park was a relatively small high school field; the league administration may have been attracted by the favorable logistics of a second team near the
Frankford Yellow Jackets in
Philadelphia. Pennsylvania's
blue laws, which prohibited football on Sundays in Philadelphia, were simply not followed in Pottsville, allowing traveling teams to play the Yellowjackets on a Saturday and then head to Pottsville on Sunday. The Maroons then jumped out to a 9–1–1 record. However some believe that having visiting teams play Frankford the day before the Maroons benefited the team. Pottsville was 5–1–0 in their six games against teams that played the Yellow Jackets the previous day. On the first snap of the game against the
Chicago Bears, the Pottsville players knocked football legend
Red Grange out cold. Grange soon recovered from the hit, only to be knocked out again. Immediately Grange said "The hell with (the $500 owed to him for the one game), it ain't worth it." He then proceeded to walk off the field. but the match only attracted about 8,000 fans, a major financial disappointment. As threatened, Carr suspended Pottsville and removed them from the NFL, preventing them from finishing their schedule.
Return to the NFL The NFL reinstated the Maroons the very
next season. The league feared that the Maroons would jump to the threatening
American Football League. In 1926
Red Grange and his manager
C. C. Pyle wanted an NFL franchise in
New York City. However, that move would have infringed on the territorial rights of the
New York Giants. Pyle and Grange were turned down, so they decided to start their own league, the AFL. To keep independent teams from joining Grange's league, the NFL hastily expanded to 22 franchises. The Maroons were one of the teams added, or in this case reinstated. That year the Maroons were once again in the thick of title contention until late in the season. Pottsville's shutout victories over the
Buffalo Rangers and
Akron Indians led to the team finishing with a 10–2–1 record and third place in the final standings. 1926 also saw the signing of
George Kenneally, a rookie out of
St. Bonaventure University, who earned all-pro status and was named team captain in just his second season, and would later become part owner of the club. However, towards the end of the season, the Maroons management struggled to meet its financial obligations, and there were published reports of a strike among the team's players. The
1927 season saw a decline in the team's on-field performance. Pottsville lost several of its stars, and others were growing older, and finished the season with a disappointing 5–8–0 record. Doc Striegel relinquished operational control of the team for the
1928 season by "loaning" it to a group of three players:
Herb Stein, Pete Henry and
Duke Osborn. Henry took over the coaching reins but the downward spiral continued. The Maroons ended what turned out to be their final season in Pottsville with a dismal 2–8–0 record. At the end of the season the players were given a small football made of
anthracite coal, a memento of the last season played in Pottsville. ==Boston Bulldogs==
